Cohn played cello in the rock group Cursive from 2001 to 2005. She left the group in August 2005. Her departure was announced on the Cursive website:
Cursive regrets to announce the departure of cellist Gretta Cohn. After four years in the band, Gretta has decided to leave Omaha to pursue other interests and projects, including a potential solo album. The split is very amicable: the band wishes her well and she in turn eagerly anticipates the new Cursive material to come. Cursive will not be seeking a replacement.[1]
She has collaborated with other artists including the band Twin Thousands. She appeared on 2006's Halloween episode of Late Night with Conan O'Brien, performing with Cat Power.
