A DIFFERENT WORLD

Has any musician ever been so comfortably inside and cosmically outside accepted jazz parameters as Anthony Braxton? Rarely played vintage compositions, new works by younger composers, and the April 17 premiere of his latest opera, Trillium J (The Non-Unconfessionables), comprise the former chess hustler and MacArthur Fellow’s Tri-Centric Music Festival, a 10-day, two-venue celebration of Braxton’s uncompromising, if sometimes frustratingly hermetic, sensibility. It kicks off at high noon today, at Eyebeam, with André Vida’s “Moving Scores (Solo Interpretations),” a six-hour series of visually interactive solos. Later, at Roulette, Braxton conducts and plays saxophone in “Composition No. 46” (1975) for chamber ensemble. Then check out tomorrow night’s “Moogie and Stetson” for 12 flutes, two tubas, and percussion.

Mondays-Sundays, 8 p.m. Starts: April 10. Continues through April 19, 2014
