Musique concrète, played live: Revolution 9
No, seriously: Alarm Will Sound has recorded an acoustic performance of the Beatles' (in)famous track "Revolution 9" (a peculiar example of musique concrète). And it is FANTASTIC. Like, really seriously the best thing I've heard in a while. It's kind of rehabilitating my opinion of the original track, actually.
Give it a listen:
Their new album is available for pre-order here. You should get it. AWS is one of my favorite musical ensembles of any kind. Their audacious and bold originality never fails to delight.
