Renee Fleming broke new ground in rock music with her 2010 album Dark Hope. With Dark Hope, Fleming took a daring detour from her classical recordings into rock music, singing with a lower register accompanied by guitar, drums, and bass. Dark Hope included Fleming's covers of songs by Leonard Cohen, Peter Gabriel, and Jefferson Airplane as well as more experimental songs, showcasing her ability to perform outside her classical genre. Critics saw Dark Hope as controversial but it demonstrated Fleming's artistry and understanding of rock.
