How many Tunisian-born German tech-house DJs does it take to make a dance floor go crazy? One, if said jock is Loco Dice. Along with the equally cunning Luciano (with whom he devastated a large crowd at this year's Movement fest in Detroit), Loco Dice unerringly finds the tracks that catalyze maximal excitement through minimalist elements. As a DJ, he converts what many consider clinical, cerebral styles into joyous, equatorial mixes. (See Sound Lounge, 115 Blanchard St, 374-3733. 8 pm, $15, 21+.)
