David Lifrieri on guitar, pedals, vocals, Jeff Knoch on farfisa organ, pedals, vocals, Erin Rosenthal on drums, percussion, vocals.
They have two official album releases through Secret Eye records which are Garden of Bones (2004), Eyelid of Moon (2005). Their sound is an intriguing combination of Krautrock improv and Psych-folk spaciness.
