Boston vocalist Brad Delp, who sang on classic rock staples like "More Than a Feeling," "Don't Look Back" and "Long Time," was found dead at his southern New Hampshire home yesterday (March 9), according to local police. He was 55. The artist was home alone at the time and there was no indication of foul play.

Delp powerful, high-register singing was an integral part of Boston's ascent to rock superstardom in the mid- and late 1970s. The group's self-titled 1976 album is often credited as the top selling debut in American history with 17 million copies; the 1978 follow-up, "Don't Look Back," shifted four million in its first month of release.

However, the band went long periods of time without new music, reappearing sporadically with different lineups. A 1986 hit, "Amanda," re-energized Boston, but Delp exited in 1991 to pursue music with former Boston member Barry Goudreau. Boston went on to release just two new studio albums in the ensuing two decades.

Delp returned to the band to sing on new songs recorded for a 1997 greatest hits album. Boston was said to have been working on a new release for the past several years, but no information has been revealed as to how far along the band was in the process.
