The winners of CTM’s annual Radio Lab call present their works tonight. Dani Gal and Ghazi Barakat consider noise and radio jamming with “Altered State Solution.” NUM (Maryam Sirvan and Milad Bagheri) create a three-part suite corresponding to past, present, and future. Afrorack, one of the first people in Africa to build modular synth setups, closes the evening with a dazzling blend of techno, abstraction, and acid.
