Dana Colley is an American baritone saxophonist from Portland, Maine, raised in Hanson, Massachusetts. He is best known as a co-founder of Morphine, the influential low-rock trio he formed with Mark Sandman and Jerome Deupree in 1989. Colley's deep, resonant baritone saxophone, often played on a vintage 1930s Conn instrument, was central to the band's spare, bass-and-sax-driven sound across albums including Good, Cure for Pain, and The Night. While Sandman served as Morphine's primary songwriter, Colley contributed compositions including Lisa, featured on AllSolos. After Sandman's death in 1999, Colley co-founded Twinemen with drummer Billy Conway and vocalist Laurie Sargent, and later formed Vapors of Morphine and Orchestra Morphine to carry forward the band's musical legacy. He has also collaborated with Lee Ranaldo, Les Claypool, Club d'Elf, and the Alloy Orchestra, and is an accomplished visual artist whose work has appeared on album covers.
