Soundchecks are a touring band’s chance to work out new material, get comfortable with a stage and, sometimes, let loose with each other (non-sexually). This week’s B List kicks off a two-part series in which we’ll feature the best soundcheck videos on YouTube. Some are hilarious, some rock, and others are simply…bizarre.

The first 10 videos follow after the jump, so read on for little-seen footage of Marley in Canada, Steve Vai showing off, Randy Rhoads rockin’ out, Mastodon, Macca, Axl Rose and more. Go on…

1. Paul McCartney plays an extremely unique version of You Never Give Me Your Money during a stop on the Driving USA tour

2. Stevie Vai shows off his stunt guitar skills during a soundcheck from a few years ago

3. Bob Marley works out Running Away with his band at Ottawa’s Civic Center in 1979

4. Randy Rhoads displays the chops that propelled him to the top so quickly during a soundcheck from Texas in 1982

5. Mastodon works out a tune with Josh Homme of the Queens of the Stone Age

6. Trey Anastasio gets radio reception over his amplifier, as Phish attempts to soundcheck in Salt Lake City
