When Pepsi tires of its Spicey spokesband, Belgium’s techno orchestra Lords of Acid will be primed to lead the teen hordes of Generation Next. The group’s glory days of “I Sit on Acid” and Voodoo-U are a far cry from the swill found on their latest release, Our Little Secret. Priding themselves on their undying efforts to stun the world with lyrical (and CD jacket) pornography, the Lords of Acid have forgotten that sex doesn’t sell by itself. The throttling, multilayered beats that sped the band to stardom are muffled on the new album by Nikkie Van Lierop’s hardly sexy, overwrought vox. Indeed, the music only manages to conjure up terrifying images of Baby Spice and Co. skipping around on a TV soundstage, belting out “I wanna see your pussy/Show it to me!” With Jack Off Jill at 7 p.m. at the 9:30 Club, 815 V St. NW. $17.50.
