Get your Neil Diamond/ZZ Top/Freddy Mercury on for Knucklehead Halloween. Kitsap County’s longest running rockers will bust up the Treehouse Cafe at 8:30 p.m. Friday with costumes and covers. Donations suggested.

At that other island enclave, Rolling Bay Hall, Space Craft presents solo sets from Acid Tongue (Guy Keltner) and Maiah Manser. That means garage band, the genre not the program, influenced by AM-radio soul, folk and psych rock before noir-pop. Show begins at 8 p.m. on the dot.

The epic trailer speaks for itself: Go watch Bainbridge High’s production of Dorian Gray, with musical interludes in honor of David Bowie. The play is 7:30 p.m. Friday and Saturday.
