If your definition of supergroup is, "A group of musicians previously associated with other musical catalogs coming together to form a new one," then the birth of a new supergroup will commence at 8 p.m. Thursday at Easy Street Records in West Seattle (4559 California Ave SW). The show is free. If you need reminding, here's a quick refresher on the players involved:
Ben Harper: You may remember him from your college days, particularly when he was fronting the dominant Innocent Criminals, a band that peaked with 1999's Burn to Shine. Lately he's been working with the less-satisfying Relentless7.
Dhani Harrison: Yes, his dad was the cool Beatle.
Joseph Arthur: Maybe you saw him at the Triple Door in January.
