I saw this performed last night at the LSO: http://www.bbc.co.uk/radio3/cutandsplice/wolfman.shtml

It's a deeply scary piece of music and Radio 3 are broadcasting it at 11pm on Saturday. If you like your Godspeed and A Silver Mt. Zion then I'd recommend giving it a listen (it was the first of the three luckily).

The other two pieces they played after had a few moments but were frankly overlong and a bit wanky. Such is avant-garde I guess.
