Andrea Parkins plays traditional instruments—piano and accordion—but makes very untraditional music. Best described as an electronics improviser or, more vaguely, a “sound artist,” Parkins has worked with seemingly every big name in New York’s downtown avant-garde jazz scene in her 20-plus-year career. Parkins’ jazz incorporates musique concrète and free and contemporary electroacoustic improvisation; the genre mouthful aside, her rock music roots show in the two aggressive collaborative albums she recorded with Wilco guitarist Nels Cline and brilliant free-jazz drummer Tom Rainey. In those, she’s as comfortable with creating bombast as she is painting pseudo-ambient soundscapes. Which side of her multifaceted talents will she choose to exhibit at the Velvet Lounge? There’s only one way to find out.
