Since 1996, Portland's Bryan Zentz has been creating ultrastimulating techno and house tracks on world-class labels like Bush, Primate, and Plus 8. In his productions, he locates the golden mean between propulsive, machinelike efficiency and libidinous rhythmic friction. If you like your club music smart and sexy (and who in her right mind doesn't?), Zentz is a reliable provider. Church of Bass offers a splendid spot in which to soak up his metronomic hot sauce. (Church of Bass, 920 Elliott Ave W, www.churchofbass .org. 9 pm–4 am, $8 before 11 pm, 21+.)
