Summertime 

Saturday is Oyster Fest — yum — see elsewhere in the Journal for full details on that fun time. I will note that The Official Afterparty takes place at Jambalaya with Roister and Free Rain, and is sure to be a super funky show given that Roister boasts Zappa alum Tom Fowler and Ray White, along with Big Tom McCree from Lyrics Born and Melvin Seals. Local all-star musicians Marcus Messina and B. Swizlo complete the quintet and ensure grooves so tasty, dancing is not an option — it's a fact. Free Rain features Piet Dalmolen of the Nucleus, Aaron Kenetic and Tomek from Moogot2, plus Tommy Fitzmaurice of the Bump Foundation. Can one venue handle so much booty-shaking? Pace yourself at O-Fest and find out. Doors at 8 p.m., music at 9 p.m., $10 cover, 21-and-over.

Friday

Sisterhood

Erika, Rachel and Chloe Tietjen compose the T Sisters (along with upright bassist Steve Height and mandolinist/guitarist Andrew Allen Fahlander), a band often compared to classic girl groups, including the Andrews Sisters and the Ronettes, but with a broader sound incorporating elements of folk, Americana, gospel, R&B, bluegrass and soul. Humboldt Brews' doors open at 9:30 p.m., music at 10 p.m., cover is $10, show is 21-and-over.

A sure bet

You can drop quarters in the slot machine and hope for a payoff or you can head right into the Firewater Lounge where Los Angeles-based psychobilly veterans the Rocketz and porch metal locals Buckshot Possum guarantee a raucous time. 9 p.m., free, 21-and-over.

Saturday

Rockabilly dreams

Why settle for one night of "–billy" when you can have two? Arizona's the Rhythm Dragons land at the Alibi to deliver a fiery blend of rockabilly, swing and punk. Joining them, Eureka's the Cruikshanks (former members of Gunsafe, current members of Smashed Glass), who play what is being referred to as "skiffle-billy folk." Music at 11 p.m., $5, 21-and-over.

Spirited resurgence

We'd be remiss to not mention Soul Night — #44, in fact —at Humboldt Brews. This one is dedicated to "the locals" — "Finally we can see the dust cloud of departing students and visiting parents which means the town is ours again." And thus, Matt n'Adam, Jaymorg and DJ Red bring you another vinyl-powered dance party. Doors at 9 p.m., cover is $5, 21-and-over.
