Mark-Anthony Turnage, the one-time bad boy of British new music, is having a momentary middle-aged grump. “I can’t understand the way some young composers are now,” he says. “They don’t have any hunger to find things out. When I was young I wanted to know all about new things like Stockhausen and Xenakis. They don’t even know the names of these pioneers, it’s amazing. I tell them it’s a tough world, you have to be totally obsessed with music and composing. If you’re not, you shouldn’t be doing it. Maybe it’s all too easy now with the internet.”
