“I am interested in sound for its impermanence, non-object nature, and structural integrity,” says Kamran Sadeghi, most well-known as composer Son of Rose, of his work. He performs sporadically and is in the same experimental school as locals Yann Novak (also on Dragon’s Eye Recordings) and Chris DeLaurenti. If you’ve tried ambient before but, perhaps, fallen asleep, I implore you to check out Sadeghi’s video excerpts on www.kamransadeghi.com. But prepare to be won over the way a Northwest winter creeps up on you: slowly, imperceptibly, effortlessly, and completely, until it looms so large you can only feel it in your life.
