Fri. July 16 -- Saharan tribal quintet Etran Finatawa groove with a real deep twangy boogie, kinda like an African Rolling Stones. Good stuff; read John Payne's article in LA Weekly here.

Fri. July 16 -- Out is where it's at with extreme vocal overloader Bonnie Barnett, who not only improvises with her skillful group (windman Richard Wood, bassist Hal Onserud, percussionist Garth Powell), she also recites from Sartre and leads an audience-participatory group hum in B-flat (to sync with those plastic horns everybody blows in soccer games).

Thurs. July 22 -- Prog metal is sweeping the planet, dude. Massive show tonight with Cynic (who praktikly founded the genre), Intronaut (an atmospheric & flowin' L.A. outfit) and New York's grinding Dysrhythmia. Three for three. At El Rey Theater, 5515 Wilshire Blvd., L.A.; 8pm; $16; www.ticketmaster.com.

Thurs. July 22 -- You seen Slake yet? The new quarterly publication founded by Joe Donnelly and Laurie Ochoa is a fun read -- $18 may seem steep, but it's got the content of four magazines, and it's all real WRITING, about stuff ranging from the rock history of the Tropicana Motel to the resurgence of avant bassist Henry Grimes (as well as plenty of nonmusic entries). Slake throws its launch party tonight with "readings, music, art, food and drink." Highly supportable. At Track 16 Gallery in Bergamot Station, 2525 Michigan Ave., Santa Monica 90404; (310) 264-4678; RSVP at rsvp@slakepublishing.com.
