It was heartbreaking to learn of the death of Christopher Gunning, although I’d been aware he had been unwell for some time.

Chris was the sort of person one felt lucky to know. He could be incredibly funny, even wicked. His vault of amazing and amusing anecdotes was second to none. As a composer for film, television and commercials, he was an incredible craftsman who took the work incredibly seriously. Likewise, his hugely wide-ranging work as an arranger for all kinds of pop stars and showbiz legends. So much so, that his doctors told him that he had to leave that world or face serious cardiac repercussions.

Leaving behind the mad deadlines of commercial music, Chris turned his enormous talent to concert music. I should say ‘returned’ his talent, because he had a deep training and grounding in classical composition, knew the repertoire inside out and had always kindled a flame to write more for the concert hall.  I became a convert when Chris sent me a recording of his monumental Fifth Symphony with him conducting the RPO. It’s a powerful and serious work – a real symphony. And it turns out, one of thirteen real symphonies.

There are also chamber music and concerti. The disc of his Violin and Cello concertos is an absolute gem. These are works that deserve a regular place on concert stages all over the world.

It was a huge honour when Christopher asked me to conduct the recording of his 2nd, 10th and 12th symphonies. We had an amazing few days recording these three powerful and varied works with the BBC National Orchestra of Wales, culminating in a wonderful and unforgettable celebration meal afterwards.

Shockingly but unsurprisingly, none of the orchestras who had recorded his music seemed inclined to programme it. In fact, not a single one of those thirteen symphonies has been professionally played live (to my knowledge) until last year.

I was so excited last year when I was able to programme his 10th Symphony, one of his favourites (and his favourite of the 3 on our CD) at Colorado MahlerFest last year. By the time the dates were in the diary, Chris was too unwell to travel to Boulder, and by the time the video of the concert was ready, he was not up to watching the performance. I so wish he could have seen the enthusiasm of the musicians and heard the reaction of the audience. In the face of the music world’s ambivalence, Chris had always had to fight his own corner and build his own projects. I’d like to think the reaction in Boulder would have helped reassure him that his wonderful music will continue to be played even though he’s no longer around to drive things.

I shall miss him terribly
