My flatmate Oli records live sessions in his ace Dreamtrak Studio in Finsbury Park, with a bunch of cameras and all the audio going into the desk, so you get studio quality audio on a live performance.
PWL just did one with alcxxk, Laura Wolf, me, ehwhat Stairs To Korea and Oli Dreamtrak all playing...
It was awesum fun :)
It's part of Andy's 15 Films project for the new PWL album. http://www.brainloverecords.com/pwl
