As part of this years Short Circuit festival at the Roundhouse, 'Ryuichi Sakamoto & Alva Noto' the be performing the premiere of a new piece of work on the 12th May.
Slight word of warning, Ryuichi's work with Alva Noto os one of his more avant-garde ongoing projects, so if you think you'll be getting Merry Chrismas Mr Lawrence or The Last Emperor, you be disappointed, (or versions you recognise anyway!).
Glad to see seats on sale in the circle, as although I am looking forward to it this is not one you'd want to stand for I think.
