Ever since Steve Reich made repetition into a compositional ethic, contemporary classical music and electronica have been learning from each other. This Saturday, the local techno-minimalist John Tejada will cement the relationship with “The End of It All,” a new piece written for a large choir and electronics debuting at Disney Hall.

Tejada made his career as a DJ and producer using brainy, handmade samples that drew heavily from the rhythmic and melodic ideas of composers such as Xenakis and Stockhausen, but all run through a filter of funk and rap urgency tailored for smarter dance floors. This show, however, will put his compositional skills at the forefront and on a much wider scale, with the Gay Men’s Chorus of Los Angeles backing his own performance on live electronics and synthesizers.

The show is a benefit for the GMCLA’s Harvey Milk Schools Project to combat anti-gay bullying in schools, and also features works by Lauridsen, David Conte and Eric Whitacre. But the night should be a grand new setting to hear one of L.A.'s preeminent voices in dance music trying on something a little more ethereal.
