Sib Hashian played drums on ALL of Boston's biggest hits, on the band's 1st 2 albums in the 1970's. He was 67 years old, playing with his band "Dirty Water" on a Legends Of Rock Cruise. Sib collapsed behind the drum kit, the show was stopped, the EMTs rushed to the stage & worked on Sib but he was already gone. What a terrible shock that must have been to his bandmates AND the audience watching the whole tragic scene unfold in front of them. RIP Sib, you did a great job on those drums on the 1st 2 Boston albums, my man.
