I free-form it, rock n' roll it. I'm a creature of risk, so I don't know how I'm going to explore a Beethoven symphony until I'm doing it.
It's Messiaen's Turangalila Symphony I'm really looking forward to. Simon Rattle does it perfectly: he understands its primal rhythmic life force, and he and the wonderful Berliners make it a sheer riot of orchestral colour.
I admire Tom Ades: he's a brilliant conductor, and he gets just the right hard, brilliant sound from the City of Birmingham Symphony Orchestra for Russian music.
