Playing what leader Mark Sandman dubbed “low rock,” Morphine got a lot of sound out of its minimal setup. The guitarless Boston trio left space between its bluesy notes, with Dana Colley’s chugging saxes, Billy Conway’s crisp drums and Sandman’srubbery two-string slide bass making an elegant rumble. Hazy and anxious at the same time, Morphine would have been high-concept mood music except for Sandman’s wry hipster crooning, full of sleazy charisma. “Candy” is a touching portrait of a self-destructive lover, while the itchy “Thursday” turns adultery into a hilarious comedy of errors. A few rarities, including the hypnotic “Pretty Face,” compensate for this 16-track set’s omission of Morphine’s two stellar major-label albums. It’s a fitting ode to Sandman, who died of a heart attack onstage in 1999 and deserves to be remembered.
