L.A. previews May 6-12: Black Label Society, Roy Hargrove, "Inquisitive Musicians," Virgil Donati, Pasqua-Oles-Erskine, CalArts percussion, Gutbucket, Symphony X, Loudness, Slumgum, Stanley Clarke.

Fri. May 6 -- Zakk's bakk with Black Label Society. BLS's new "The Song Remains Not the Same," which comes out Tuesday, will send the berzerker legions back to Wylde's 1994 days with Pride & Glory -- the country-rock plod with deep bows to Neil Young. Me, I'm down with Neil and enjoy hearing Zakk knock out semiacoustic versions of his megaton metal crunchers from last year's deadly "Order of the Black." His covers of "Bridge Over Troubled Water" and "The First Noel" . . . not so much. With modern melodic metal pussies All That Remains and Hourcast. (Zakk needs to get better openers.)

Fri.-Sun. May 6-8 -- I dig trumpeter Roy Hargrove's playing, I just think he wears too many hats (soul, hip-hop, almost pop). In this jazz-club context, he'll probably hover around the traditional post-bop he's best at.
