POP STARS:***** Great Balls of Fire: **** Knockin’ On Heaven’s Door: *** Good Vibrations:** Maybe Baby: * Ain’t That a Shame : Alyson Williams “Raw.” Def. JAM/Columbia. ***

There are plenty of R&B; -style numbers on Harlem-born Williams debut album that sound OK without quite reaching knock-your-sock-off territory. There are a few cuts, however, that are so low-down and no-nonsense that they force you to sit up and take notice-like the dance-oriented “My Love Is So /Raw,” which features and abrasive and tough-rapping Nikki D. Funny and oh-so-hardcore, Willams has a confrontational style that’s closer to Millie Jackson than Miss Manners. She turns on the chill factor again on “Sleep Talk”-remixed by Public Enemy Producers Hank Shocklee and Eric (Vietnam) Sadler-as she icily informs her -philandering bed-mate, “You keep on sleep talking”/ Pretty soon you’re gonna be street walkin’.” With her soulfully commanding vocals and penchant for combative funk, Williams is a salty alternative to such sweet divas as Pebbles and Paula Abdul.
