David Grisman and Del McCoury 2/25/16 College St. Music Hall

Bluegrass pioneers Del and Dawg graced the Hall with history and chops. At 79, Del got his start on banjo and then rhythm guitar for Bill Monroe in the 40s. Grisman on mandolin played with Jerry Garcia. With one microphone, Del and Dawg played some staples: Dark Hollow, Toy Heart, Shenandoah Breakdown. Between songs, mainly Grisman taught a master's class on the history of bluegrass. The audience offered the pair a church-like reverence, realizing that these two are in the waning moments of their touring careers. Show highlight was Man of Constant Sorrow.
