Featuring drummer Roger Travassos and bassist Steve Zsirai, the group issued their debut album, titled "Suites", on Diamond Gem Records in 2012.
About The Donna Grantis Electric Band, Donna describes the group’s approach to improvisation as:
"Creating music in the moment, reacting to each other on stage, exploring musical themes for extended lengths of time, and utilizing effects pedals to broaden the tonal pallet of the music. The creative intention is to be free and continuously challenge each other on stage. Hopefully in doing so, we can create an experience for listeners and take the audience on a musically engaging journey."
