Blizzard of Blues III returns to Arts Collaborative Medford on December 12 for a night of high-energy blues in support of Down By Riverside. Produced and headlined by acclaimed blues-rock artist Johnny Williams, the show brings together 20 musicians from the local music community — all donating their time and talent — across an opening mini-set and three full sets featuring Mark Hobbs, Steve Koulalis, and Johnny Williams himself, culminating in an all-star jam finale led by vocalist Lexy Lattimore. The night also honors the tireless community work of Hendrik Gideonse, whose dedication has helped build and sustain the local music scene that makes a show like this possible. Every ticket sold helps fund Down By Riverside's mission — come for the music, stay for the cause.
