My eyes and ears perk up when I see the names Jan Jelinek and Frank Bretschneider—even if it's in an e-mail from an unknown electronic outfit. Such was the case with San Francisco's Mem1 (Laura and Mark Cetilia on cello and electronics, respectively), who cold-contacted me about a show they're playing at the Rendezvous on Thursday. They mentioned their new CD involving collaborations with those two genius minimalist producers, plus seven others, including Steve Roden. As it turns out, that disc, +1, burrows into microscopic furrows in the stereo field, tickling the most delicate cilia in your ears and forcing you to focus mightily on the subliminal friction between catgut and silicon chip. At times you feel as if you've been inserted into somebody's body and can hear their internal organs (mal)functioning. The prevalent mood is mournful yet tranquil, evoking the aftermath of a tragedy and the resultant calm; think of the music moving from wah to aaahhh, very gradually.

Similarly, Sun Circle (Greg Davis and Zach Wallace) explore beatless space, but in a more expansive manner. Whereas Mem1 score the body's inner gurgles and expirations, Sun Circle, as their moniker implies, radiate solarized drones that wax and wane in intensity in subtle increments. The sound is akin to that of Davis's Kranky Records labelmate White Rainbow: Cursory listens could trigger knee-jerk accusations of "new age"–ism, but the music of both artists is too interesting and psychedelic for that tarnished term. More accurately, Sun Circle create a rarefied, spiritual strain of healing music whose only gods are Terry Riley and Pauline Oliveros. Check out Sun Circle's split 12-inch with Eleh, Fading Spectrum of Darkness/Parhelion (on Important Records), for ample proof of their gently ecstatic, peace-inducing vibe rations.

By contrast, DJ T. (Germany's Thomas Koch, founder and publisher of the taste-making magazine Groove) is a beats man, one in high demand globally for his productions and deck-rocking capabilities. He's also one of Get Physical's bosses, so he has dexterous fingers on the pulses of house, electro, and techno's international elite. With over two decades of DJing experience, T. should provide a mobile, exuberant musical lesson in those and other genres. Expect a lot of shiny shirts to need wringing out by night's end. recommended
