It is with great sadness to report that former Boston drummer Sib Hashian has died.

Sib was performing on stage Wednesday night on the Legends of Rock Cruise when he collapsed. Medics on board the ship attempted to recuscitate him using CPR and a defibrillator, however were unable to revive him.

Sib, who was born John Thomas Hashian, joined Boston in 1975 replacing original drummer Jim Masdea. Sib played drums on the first two Boston albums. He also performed on Barry Goudreau's 1980 solo album prior to his departure from the band. Sib joined Barry many years later as a member of the band Ernie and the Automatics. Sib was taking part in the Legends of Rock Cruise, along with various musicians, including Lou Gramm, John Elefante, as well as Barry Goudreau and Ernie and the Automatics bandmate Michael Antunes. The cruise began March 18 for a one-week voyage, making stops in St. Maarten, Puerto Rico and the Bahamas.

No funeral arrangements have been announced at this time.
