The lead singer of the Boston rock band Morphine, Mark Sandman,

died of a heart attack suffered onstage during a concert outside Rome

on Saturday night, according to an Associated Press report. He was 46.

The singer/bassist for the group known for its mostly

guitarless beat-noir sound collapsed onstage in front of several

thousand spectators at a music festival just before midnight, AP

reported. "We're devastated," band manager Deborah Klein was quoted as

saying Sunday. "We don't even know what to say. We're all in shock."
