Ash Grunwald knows how to get the most out of the beautifully basic tools of the blues; in 2002, Introducing Ash Grunwald came out with a mixture of originals and covers of the likes of Howlin' Wolf, Elmore James and Robert Johnson. He recorded it live with just an acoustic guitar, stomp box and tambourine. The 2004 followup, I Don't Believe, got bigger and bolder, featuring junkyard percussion beneath his guitars. Over the years he's continued to evolve, offering fiery live albums and a number of hard-grooving studio outings. Trace his evolution through this playlist of his best tracks.
