Trumpeter Dave Douglas is, like a lot of his jazz brethren, a very busy man. Since the late ’80s he’s been a fixture in the New York scene, applying his sharp tones and improvisational daring to groups like John Zorn’s Masada, albums by artists like clarinetist Don Byron and experimental pop group Cibo Matto, and his own far-ranging discography. He’s also leading the charge for artists rights through his fantastic label Greenleaf Music, which uses a subscription model to stay afloat and provide a steady source of income for its musicians. This year alone, Douglas has released two albums of original material: a new collaboration with Detroit electronic artist Shigeto and a dada-inspired work recorded with pianist Frank Woeste. We’re lucky to get a glimpse of him here in Portland for one brief evening, where he’ll appear with the brass-heavy ensemble the Westerlies. ROBERT HAM
