The sheer breadth and depth of this collection speaks of the years Peter Mulvey has spent avidly, joyfully honing his craft; soaking up the juju of masters past and present, and (like a knuckleballer) attending to details. File the fingernails. Practice the scales. Stretch the arm. Listen to Louis Armstrong and Latin Playboys. Learn ten Ellington tunes; twenty by Greg Brown. Call your friends and argue about art. Play. Play music on stage and off, day and night.
