My concertgoing for the remainder of the week is taken up with Steve Reich events — the Young Artists Concert tonight, the grand concert on Saturday, Discovery Day and the Daniel Variations premiere on Sunday — and I'll have to miss other things that look distinctly promising. Tonight at Angel Orensanz the Metropolis Ensemble opens its second season with David Schiff's All About Love — "a panoramic meditation on love as expressed in different times and languages and from different points of view: male and female, gay and straight, from youthful ardor to mature resignation" — and Monteverdi's eternally entertaining Il Combattimento di Tancredi e Clorinda. (Schiff is also a brilliant critic — read his piece on Reich in The Nation.) On Friday and Saturday nights, the incontestably kick-ass Alarm Will Sound will do $12 shows at the Kitchen, with repertory ranging from Johannes Cicconia to Nancarrow's player-piano pieces and on to Birtwistle. Two events at Joe's Pub: on Friday, Brad Lubman, who offered fiercely expressive video-linked acoustic-and-electronic music at the recent American Composers Orchestra show, plays with his band Electric Fuzz, and on Sunday Ethel presents music of John King. Meanwhile, the blögøsphère's Jeremy Denk serves up late-night Bach at the Kaplan Penthouse, possibly with naked supermodels, or so he hinted in a recent post. We do hear things have been getting pretty wild up in the Kaplan Penthouse lately: these innovative, late-night classical concerts are raging out of control, and the neighbors might have to call the police.
