Menomena are an experimental rock band from Portland, Oregon, made up of Danny Seim on percussion; and Justin Harris on bass, guitar, and saxophone. Both members of the band share singing duties and swap instruments frequently while recording. The band formed in late 2000, when ex-member Brent Knopf graduated from Dartmouth College and returned to Portland to collaborate with Harris and Seim. They played their first show in July 2001, at The Meow Meow, a now-defunct all ages venue in Portland.
