LOS ANGELES

IF he were not already recognizable for his gaunt frame or the distinctive W logo on his baseball cap, it would have been easy to spot Robert Diggs — better known as the RZA, the actor, rapper and mastermind of hip-hop’s Wu-Tang Clan — by the haul of vintage records and DVDs he was toting here at Amoeba Music.

Wandering between the black cinema and martial-arts video aisles, RZA thumbed through titles he already owned (“Cleopatra Jones and the Casino of Gold”) while picking up some new additions for his collection (a boxed set of action movies produced by the Shaw Brothers of Hong Kong).

Before he exited with $402.94 in purchases, heavily tilted toward Asian action films, a smiling RZA said in his quiet voice, “You can’t say I’m not supporting the cause.”

Based solely on his Wu-Tang years, when he channeled his youthful obsessions with movies like “Five Deadly Venoms” into potent rap albums like “Enter the Wu-Tang (36 Chambers),” RZA, who is 43, would seem to possess unquestionable kung fu credentials.
