Music in Darkness marks the Texas premiere of "in vain," the monumental masterpiece by contemporary Austrian composer Georg Friedrich Haas. He composed the piece so that the parts would be easy to memorize, the music could be controllable by ear, and so it would work even without a conductor's visual cues. The microtonal score will be performed by the 28 musicians of Loop38, punctuated by an immediate burst of light, on the serene grounds of the Rothko Chapel. The fairly new chamber ensemble, co-founded last year by conductor Jerry Hou and pianist Yvonne Chen, consists almost entirely of Houston transplants, though it seems they got here as fast as they could.
7 p.m. May 2. 3900 Yupon. For information, call 713-524-9839 or visit rothkochapel.org. Free; $10 suggested donation.
Don't expect any egotistical divas at this concert, which calls for musicians to perform without sheet music in almost complete darkness so that viewers listeners can better concentrate on the melodies and sounds.
