A prime (non)mover in ambient music and new age circles, Robert Rich has been relieving tension and lifting spirits through sound for 30 years. His vast catalog encompasses releases whose contents range from the closest thing to holy vapor that instruments can approximate to more full-bodied, serpentine compositions evocative of the lush, cinematic work of Vangelis and Goblin. A rigorous minimalist, Rich nevertheless imbues his music with a sublime tonal and melodic beauty. He'll be supporting his gorgeous, blissful new album, Ylang. (Chapel Performance Space, 4649 Sunnyside Ave N, fourth floor, 789-1939. 8 pm, $5–$15, all ages.)
