My Audio World: Simon Allen 

Tubular Bells 50th Anniversary.

We always look forward to chatting to our friend Simon Allen. Simon is an internationally recognised Professional Sound Engineer whose recording, producing and mixing skills have seen him work with a host of prestigious names: A.R. Rahman, Mila Kunis, The Sweet, Helen Jane Long, Birmingham Royal Ballet, Dame Evelyn Glennie... to name but a few.

Most recently Simon has taken on the esteemed role of lead recording engineer, co-producer and mixing engineer roles for the Official 50th Anniversary of Mike Oldfield’s Tubular Bells with the Royal Philharmonic Orchestra.

This once-in-a-lifetime opportunity encompasses Simon's full wealth of knowledge and he took some time out to tell us a bit more about this exciting new project.


Hi Simon, what a fantastic project to be working on! Could you tell us how it came about?

Mike Oldfield’s revolutionary Tubular Bells album was released back in 1973 and gained worldwide attention after being used as the soundtrack for the film The Exorcist.

Today, Tubular Bells continues to sell over 100,000 albums per year. Ahead of the 50th Anniversary in 2023, Kaleidoscope have commissioned several live performances, a documentary feature narrated by Bill Nighy and a new studio recording with the Royal Philharmonic Orchestra. It’s this new studio album that I was asked to work on, which is especially significant as the Royal Philharmonic Orchestra released The Orchestral Tubular Bells in 1975.

Although the 1975 recording with the Royal Philharmonic Orchestra is highly revered, it didn’t include the famous ‘Master Of Ceremonies’ and vocal sections heard on the original. This newly commissioned work features the Royal Philharmonic Orchestra, some of the greatest contemporary session musicians in the UK, a full choir and Brian Blessed as Master Of Ceremonies and the formidable Caveman in part 2.

Utilising modern recording techniques, it has been put together to celebrate these remarkable works including; Tubular Bells Part 1 and Part 2, Ommadawn Part 1, Hergest Ridge and Moonlight Shadow in a double vinyl and digital release.

Tubular Bells is such an iconic album and was completely groundbreaking. Released in 1973 when there was no computer technology and everything was recorded on 24 track with Mike Oldfield playing all the instruments. How does recording this album in 2022 look and what shape will it take compared to the original?

Absolutely, besides the composition itself and the instrumental nature of the work, the fact Mike Oldfield recorded the original at the age of 19 and played the majority of the instruments himself via 274 overdubs was equally groundbreaking. This new work is aimed to celebrate this incredible composition using modern recording techniques. We have tried to capture the essence of the original while breathing modern sonic capabilities into the mix. I hope any music lover or audiophile will enjoy something fresh while still retaining the nostalgia. Although we have the wonders of modern technology, I can assure you the work put into this project is unlike anything I’ve done before!

What are some of the most exciting challenges you’ve faced so far?

Due to the nature of these compositions which encompass unique instrumentations and a mix of styles, bringing all these elements together as a concise picture has been my focus throughout. Perhaps less exciting, but even more critical for my role in this project however, has been good organisation. We captured this double album at a high sample rate (high quality) and have consistently focused on the quality of every capture. As any engineer will tell you, that leads to careful planning of parts through to data management and utilising processing power. We are spoilt with the processing power available today, but I wanted to bring out the best possible result without cutting any corners.

You’ve got some huge names playing on this album – could you tell us a little bit more about them and what you think they bring to the project?

Obviously the Royal Philharmonic Orchestra need no introduction. However, having worked with many recognised orchestras and session orchestras before, I can’t stress enough how good they were on these sessions. Not only were they highly professional as you would expect, but the musicality and detail in their playing, even on initial takes, was often beyond expectations. Arranger Simon Dobson who also conducted the orchestra and choir, as mentioned earlier, has been vital to this project. We very quickly found a natural rhythm and established a strong professional relationship while working on this project. I believe he is one of the special ones and wherever you see his name in future it’ll be a project worth checking out.

Name-check wise, Brian Blessed has been an obvious choice for this project, fulfilling Master Of Ceremonies and Caveman duties. There probably aren’t many better fits for this role and we’re incredibly lucky to have captured him on these recordings.

There are many highly talented musicians on this project, but the key contemporary parts have been recorded by some of the UK’s greatest talents today. All guitar and mandolin duties have been carried out by Pete Callard (Lionel Richie, Queen, Annie Lennox, The Bee Gees...), the famous bass lines are re-played by Andy Pask (Madonna, Pet Shop Boys, Shirley Bassey, Tom Jones...) and on keys and piano we have the incredible Jeff Leach (Strictly Come Dancing, X-Factor, Brian May, Royal Variety...)
The percussion parts, which are far greater than you might first imagine as well as the “Tubular Bells” of course, were played by Kevin Earley (Lord Of The Rings, Royal Ballet Sinfonia, Live Earth...) and Tom Edwards (Royal Academy Of Music, Royal Ballet Sinfonia, LSO...).


Tubular Bells has a timelessness to it and it is incredible to think it was released in 1973 – is that something you are aware of when you are in the studio working on it?

Absolutely. I still remember my father having the original vinyl with its unique cover art when I was younger. He would play it on Sunday afternoons as my Mum cooked the Sunday roast. Every time I opened the project to work on it, whether it be recording a new part or to simply carry out some editing, I have been quickly reminded of the awesomeness before me. Interestingly, my mother and father have very different musical backgrounds and rarely are they both interested in the same projects that I’m working on.

With this however, they’ve both been enthralled, which to me demonstrates the reach of this amazing material.

What do you think will be the highlights of this epic project?

Hopefully it’s the joy of listening back to such an exceptional piece of music that’s still unlike almost anything else. I hope it will appeal to those that love the original as much as it will anyone coming to it for the first time. With the pieces being quite long, I hope it breaks the modern cycle of skipping through a playlist and giving the listener some escapism from day-to-day life. I’ve certainly been lost in it all for a while, which has been an honour and a joy.


Lastly - could you tell us what your favourite Flare product is?

That's a tough one! I was first introduced to Flare Audio via the large-scale line array X5 system which cemented my fascination in the products. Apart from hearing some phenomenal results over the years from their speakers such as Flare Zero, their IEMs: Flare Pro’s and Flare Pro Gold have been in my gig bag ever since.

But the all-new E-Prototypes demonstrate that in fact Flare Audio were only just getting warmed up! This new IEM design completely recalibrates our understanding of a natural response.

With a project as extensive as the Tubular Bells 50th Anniversary Celebration, (which unsurprisingly uses a significant channel count and now spans a double CD or 4 sides of vinyl) the editing process requires countless hours of concentration. To be able to make critical editing decisions on such detailed in-ear headphones such as the E-Prototypes, allowed me to work more freely, away from the studio environment and manage my time more flexibly.

When it came to the mixing process, as most engineers do, I begin the tonal and balancing process on studio monitors. However, when making decisions about stereo placement, I often like to check this on headphones. For me, the E-Prototypes excel in replicating the stereo image, and were critical in aiding the choices I made. This is particularly notable for this project as the imaging is both governed by the Royal Philharmonic Orchestra layout, as well as creative choices that span back to those of Mike Oldfield. Furthermore, with complex harmonic structure and instrumentation spread across the stereo field, the final balance was certainly the hardest aspect of mixing this wonderful album. I will be forever grateful to have had the E-Prototypes to hand throughout this special and unique opportunity. I only hope the results speak for themselves, bringing both an immersive and detailed soundscape to this classic.


Thanks so much Simon! We can't wait to hear it.
