The founder of a floating concert venue that has been part of the Big Apple’s music scene since 1977 has died.

Olga Bloom, the founder of Bargemusic, died Thursday at age 92.

Her death was confirmed yesterday by Bargemusic director Mark Peskanov.

Bloom was 57 in 1976 when she gave up her career as a violinist and violist to create Bargemusic.

She converted an old coffee barge into a concert hall moored to the Fulton Ferry Landing in Brooklyn. She once said she wanted to create a place for musicians to perform in an environment that would nurture them.
