I've been watching Youtube's live broadcast for the past two days. There's some really great music playing. Check it out tonight. There's 3 channels and it looks real nice in HD at 720p or 1080p. I really hope Youtube releases the broadcast of all the performances.
From Friday, I liked Metric, Yeah Yeah Yeahs, How to Destriy Angels, Teagan and Sara, Beardyman, Jello Braton, Infected Mushroom.
From Saturday, I liked Portugal the Man, and Hot Chip. They had a lot of club DJs too and the best one was Diple from the band Major Laser.
I have yet to watch Sunday's broadcast.
You can move the slider back if watching live which is what I do. They do a rebroadcast which takes it into the early hours of next day. Then the video is gone.
