Dawn of Midi’s 2013 sophomore album, Dysnomia, is repetitive to the point of unbelievability. Notes and phrases are repeated to a bewitchingly intense level, with gradual, subtle shifts in rhythm and melody. While initially redundant, the sound eventually becomes hypnotic. At base, it’s minimalist, ambient electronica, but made using the acoustic instruments of a jazz trio — a grand piano, an upright contrabass, and a drum kit. But Brooklynites Aakaash Israni, Amino Belyamani, and Qasim Naqvi don’t sound anything like a jazz group, and they don’t improvise: Every note on Dysnomia is calculated. Watching them live should be a transfixing experience. See them at The Chapel (777 Valencia St., San Francisco) on Sunday; Australian alt-pop duo Big Scary will open the show.
