East Rock Klezmer was born out of a shared love of traditional Jewish music.

East Rock Klezmer strives to remain true to the "old-world" Eastern European sound while honoring the musical sensibilities of contemporary audiences. One can hear ERK at private simchas and local venues in the Greater New Haven area. During the school year, East Rock Klezmer occasionally appears in functions at Yale University, playing in services at the Divinity School's Marquand Chapel, and at parties at the Slifka Center and the Botanical Gardens. During the summer, the band frequents farmers markets and the benches in East Rock Park, for which the band was named.
