The David Grisman Quintet, as any hippie/jazzbo hybrid can tell you, plays “dawg” music. That’s a heady blend of bluegrass, swing, Django-inspired gypsy jazz and assorted Latin flavors. For the uninitiated, track down the latest release on Grisman’s Acoustic Disc imprint: a two-set gig recorded at Seattle’s very own Jazz Alley in November of 2007. Speaking of Acoustic Disc, the label has also released, for the first time ever, the complete Old & In the Way concert. In 1973 Grisman hooked up with Jerry Garcia, Peter Rowan, Vassar Clements and John Kahn for a one-off performance that helped kick start the progressive bluegrass movement. Old & In the Way are far more folk-oriented than the Quintet, yet both groups embody Grisman’s profound love of improv.
