Sonic Circuits has come a long way. At the experimental music festival’s inaugural year in ’02, a few local noiseniks gathered in an auditorium at the Levine School of Music to bang on treated guitars and homemade synthesizers. Percussionist Ikue Morie, the festival’s star attraction, performed an improvised composition with laptop artist Chuck Bettis. The set lasted only 20 minutes and both parties looked enormously bored. But with each year since the festival has dramatically improved. This year’s weeklong event has one of the best lineups yet—pairing local talent with krautrock pioneers Faust, percussionist Pilesor, and Canadian computer-music guru Tim Hecker.

NINE STRINGS AND PILESOR PERFORM AT 6 P.M. AT THE KENNEDY CENTER’S MILLENNIUM STAGE, 2700 F ST. NW. FREE. (202) 467-4600.
