This is a bummer.

Founding Blue Öyster Cult keyboardist and guitarist Allen Lanier has died.

He passed on Wednesday of chronic lung disease at the age of 66.

“We have extremely sad news to report,” writes the band online.

“We’ve lost our friend and bandmate Allen Lanier. Allen succumbed to complications from C.O.P.D. [Chronic Obstructive Pulmonary Disease].”

Allen is survived by his wife Dory, sister Mary Anne and mother Martha.

“Although he retired from touring in 2006, Allen returned to the stage for what turned out to be his final appearance, reuniting with Blue Öyster Cult at the 40th-anniversary show in New York this past November.

“[Don’t fear the reaper] sweet man. We love you and miss you.”
