Six hours onstage, with no intermission and rests barely long enough to sip water. Sounds more like Marina Abramović performance art than a chamber music concert. But that’s precisely what the daring local ensemble Spektral Quartet will undertake on March 11 at 6 p.m. at the Museum of Contemporary Art Chicago when the group performs Morton Feldman’s formidable String Quartet No. 2. Lasting somewhere between five and just over six hours, Feldman’s work is the longest in the canonical string quartet repertoire. Here, in anticipation of the performance, the four musicians detail their seven steps for survival.
Pig out
At about 4 p.m. on the day of the event, eat enough to last eight hours. Protein over carbs, which might make Feldman-induced serenity (he’s known for quiet pieces) tip over to food coma.
