noon Block Party

The Sunset Junction Street Fair, which annually turns a stretch of Sunset Boulevard in Silver Lake into an eclectic block party, marks a quantum leap in musical ambition in its 22nd year. Building on its established foundation of L.A.-based talent, the two-day event also features such nationally prominent rock acts as Sonic Youth and Mudhoney (Saturday) and Sleater-Kinney and Pansy Division (Sunday). Beyond the rock, there’s the usual array of soul, ethnic and electronic music.

Sunset Junction Street Fair, 3600-4200 Sunset Blvd., L.A., Saturday and Sunday, noon. $6. 661-7771.

8pm Dance

Is performer-choreographer-producer Deborah Brockus the single most important person in Southland dance? Certainly nobody else is presenting more locally based artists more times during the year: student dancers in one of her series, multimedia specialists in another and just about anyone and everyone in “Spectrum,” now in its 12th edition and still an amazing grab bag of short pieces. Besides Brockus, the new version is notable for including choreographer Jamie Nichols, who danced off with three Lester Horton Awards recently. Other participating dance makers include Gustavo Gonzalez, Lisa Lock, Ken Morris, Anna Djanbazian, Denise Leitner, Cati Jean, Sarita, Loren Denker-Slutsky and Brian Frette, Kevin Farnsworth, Elizabeth Hoefner, Mark “Swany” Swanhart, John Castagna, Eric Henderson, Shelly Puente, Dani Lunn and Erin Hirsh.

“Spectrum, Dance in L.A. #12,” Ivar Theatre, 1605 Ivar Ave., Hollywood, 8 p.m. Also Sunday, 7 p.m. $15 (advance purchase), $20 (day of performance). (310) 645-9419.

Kidjo, who is fluent in French, English and Yoruba, will collaborate with her husband, bassist-producer Jean Hebral, to meld her vocals to African pop, Caribbean and Congolese rumbas and cumbias, jazz, zouk and funk rhythms.
