Usually, the Rivertown Poets offer an open mic along with their monthly “A-Muse-ing Mondays” reading event, but this week the bill is just too packed. That’s because this installment includes the release party of “POETRY+JAZZ: A Magical Marriage,” the new audio book by local publisher Sher Music Co. that matches world-class poems with jazz compositions. Publisher and Petaluma local Chuck Sher will host the evening’s events, with Bay Area poets Gary Turchin and Dave Holt delivering readings. The Aqus Cafe gets musically amusing on Monday, July 6, at 189 H St., Petaluma. 6:30pm. Free. 707.778.6060.
