For Latin Lovers Bobby Matos' first record, My Latin Soul, is so rare and so popular that jazz collectors and DJs are willing to pay huge sums to get their hands on it. Otherwise, Matos -- who's been playing since the '60s -- remains something of an underground hit. His 1995 album, Chango's Dance, is a lyrical, lively selection of mambo and rumba numbers played on new and traditional instruments and sprinkled with Cuban poetry narrated by actor Ismael Carlo. The Bobby Matos Afro-Cuban Jazz Ensemble plays at 9:30 p.m. at the Elbo Room, Valencia at 18th St., S.F. Admission is $5; call 552-7788.
Dive In The long-awaited final collaboration between modern choreographer Merce Cunningham and composer John Cage, Ocean, makes its U.S. premiere at UC Berkeley. The Merce Cunningham Dance Company is joined by a 112-piece orchestra for this evening-length work, to be performed in the round. Cunningham and Cage upset and inspired decades of dance watchers with their unorthodox creations; since Cage's demise, this is the last unseen product of their partnership. Ocean replaces a previously announced mixed-repertoire program. Show times are 8 p.m. tonight and Saturday at Harmon Arena, Bancroft & Dana, Berkeley. Admission is $12-22; call (510) 642-9988.

He and his 14-piece band fire off Afro-Latin originals from his newest release, Sonero del Mundo, at two salsa dances, 8:30 and 11 p.m., at the Great American Music Hall, 859 O'Farrell, S.F. Admission is $25; call 885-0750.
