On Gary Burton's debut release on Mack Avenue Records Common Ground, the Grammy-winning pioneer of the four-mallet technique of playing the vibes is not only delivering his first studio album since 2005, but is also introducing his latest band. Well-known throughout his five-decade career for his quartets (beginning with his 1967 group featuring Larry Coryell, Roy Haynes and Steve Swallow), Burton is returning to the configuration for the first time since the mid 90s. He expresses great enthusiasm for the new band's alchemy. I've always liked the vibraphone-guitar sound, says Burton, whose masterful vibes glisten throughout Common Ground. It's something that I discovered when Nashville country guitarist Hank Garland invited me in the 60s to record with him. The sound of the two instruments together has an ideal timbre and coolness.
