Last year's Above the Rim, 1993's Judgment Night – certain soundtracks have deftly showcased rap innovation. Accompanying the new comedy penned by Ice Cube and partner D.J. Pooh, Friday isn't an equivalent landmark, but it's a righteous set. New cuts by Dr. Dre (in characteristic slow simmer), the ever horny 2 Live Crew, Scarface (menacing as always) and Cube himself are standouts. Cypress Hill turn in a soggy joint; lesser knowns like Threat and the Alkaholiks almost steal the thunder from the big names. And for smooth relief, there's polished R&B (the Isleys, Rose Royce). Check out Roger, too. He manages a near miracle: breathing fresh life into "I Heard It Through the Grapevine." (RS 707)
