Bassist Ethan Philion takes a respectful, well-researched approach to the music of Charles Mingus. This busy Chicago freelancer, with degrees from Oberlin and DePaul -- and a long list of other accolades -- arranges this music always with an ear toward the composer's intent. His band, Meditations: the Music of Charles Mingus, often appearing as a ten-piece ensemble, will be showcased on the Garver Patio as a quartet featuring Russ Johnson, Alexis Lombre, and Dana Hall.
