You might call it the mark of a good songwriter – every song is different, but they somehow all sound like they were written by the same person. In this case, the person is Chris Grunwald, whose eclectic Americana ensemble Griz recorded a Key Studio Session just about a month ago that dabbled impressively in shuffling rock ‘n roll (“Plant Life”), psychedelic folk (“The Secret in the Garden”), pulsing reggae (“Only Dreadlock”) and twangy country (“Take Me On the Road”). Griz has been an understated fixture in Philly in recent years: Grunwald doesn’t loudly call attention to himself, but simply does what he does – plays shows, makes albums (most recently last year’s breezy The Secret in the Garden) and has steadily built a following around the Delaware Valley. You can download band’s Key Studio Session below. If you dig what you hear, you have two chances to catch Griz live in the next couple weeks: at the AC Beer and Music Festival on Saturday March 31, and at MilkBoy on Thursday April 5.
