MSTRKRFT's name doesn't surrender the secret of its sound readily. Its letters at first are incomprehensible but upon enunciation, the coherent utterance is Master Kraft. Despite this accepted pronunciation, the presence of different letter groupings suggesting different names-miss trick raft, my streaker feat-assert the potential for endless variation. These possibilities latent in this DJ duo's name characterize the nature of their turn-tabled tunes. Each presents so expansive a soundscape that ears primed to hear different sounds will and do. Fans of the song remixed hear that first, electronic fans hear the house-handclap synth sounds as the fore, dancers feel the floor beat out a bass that other fans recognize as that from another band's hit-single. The bass ushers that hit-single to the main track position. A new balance among the elements realigns the audience's roles, the dancer now familiar with the song, the fan now working her calf muscles, the twitch-dancing techno fan now as grounded as the bass. The thrill of role-playing courses through the crowd as everyone bounces and jumps into a new identity.

Conducting these identity crises, MSTRKRFT seemed more the algorithm than the artist: a notoriously outspoken identity-type silenced in band members Jesse F. Keeler and Al-P. The two producers closeted themselves behind mixing tables and let the music speak for itself. Fitting, then, for the band to assume the name Master Kraft. Kraft doesn't designate a proper name but rather an activity or an art, and so Master Kraft refers less to the two men working their machines than to the mixes that issues from their speakers, the lights that illuminate the stage and their sound's effect on sonically seduced fans.

The dashing duo keeps a black book bursting with the globe-encompassing digits of the devoted. Hailing from Canada, the band has performed at America's Bonnaroo in 2008, tours regularly throughout the United States and maintains a fervent fan base abroad. For example, the night's best dancers were two Swedish girls who included a travel stop in San Francisco for the express purpose of watching MSTRKRFT perform.

That black book no doubt includes the numbers of musicians whose tracks the band has remixed, from Usher's "Love in this Club" to Bloc Party's "Flux" to fellow freshly-risen electronic outfit Justice's "D.A.N.C.E." That these musicians all have devoted listening blocs further proves the extent of MSTRKRFT's appeal. In the same way that "Sure, sex is good, but have you ever tried it on E?" MSTRKRFT amplifies the highs of a well-known song to make it that much better.

Joining MSTRKRFT for the Fist of God tour, opening acts Felix Cartal and Congorock tamely tested the audience and stage lights. The typical trance trajectories of their songs, predictably charted climaxes and low-envelope, high-volume midrange effects served more to limber dancing muscles than engage ears. When MSTRKRFT took the stage to lights burning as brilliantly as Mt. Horeb's bush, the fist of god truly struck. As the night wore towards 3 a.m., bodies became hollow sound boxes echoing the speaker's vibrations. The crowd created its own dynamic equalizer of the audio, bursting into red with excitement before dropping down, away from the lights, to a jean-grinding green level, every individual measuring the music according to his or her unique frequency. MSTRKRFT's set closed the night with a non-stop, light-flashing episode of epileptic ecstasy.
