Mark Hummel’s Blues Harmonica Blowout celebrates more than 30 years of national and international festivals and sold-out venues coast to coast. The Blowout began on a Sunday night at the Ashkenaz in Berkeley in 1991 with four harmonica players Rick Estrin, Mark Hummel, Dave Earl and Doug Jay and has since become a “Who’s who of the Blues,” featuring the top harp blowers around. Blowout tours have visited every part of the US, Canada, and Europe, carrying the blues torch to fans everywhere. Come jam with the best of the best as the Blues Harmonica Blowout comes back to Medford!
