Morphine was an alternative rock group formed by Mark Sandman and Dana Colley in Cambridge, Massachusetts, USA, in 1989. Morphine combined blues and jazz elements with more traditional rock arrangements, giving the band a very unusual sound. Sandman's distinctive singing was described as a "deep, laid-back croon," and his songwriting featured a prominent beat influence. When asked by reporters to describe their music, the band created the label "low rock". One critical appraisal suggests that "Morphine immediately established a minimalist, low-end sound that could have easily become a gimmick: a 'power trio' not built around the sound of an electric guitar. Instead, with sly intelligence, Morphine expanded its offbeat vocabulary on each album."   Wikipedia
