A fiddle is just one of many instruments that will be heard in Sebastopol’s Ives Park this month. There’ll also be plenty of guitars, drums, bass, and even a djembe. Each will come to the stage as part of the annual Peacetown free summer concert series. Onye and the Messengers will play African jazz-fusion on August 7, Volker Strifler will deliver original rock tunes on August 14, Tom Rigney and Flambeau will churn out Cajun zydeco on August 21, and, on August 28, Poor Man’s Whiskey will perform rock n’ roll bluegrass. Shows are held 6–8 p.m. See peacetown.org for details.
