Cosmic Jerry Band is a high-energy, Grateful Dead–inspired quartet blending deep musical experience with fearless, in-the-moment improvisation. Featuring Ty Mares (guitar, vocals), John “Jelly Roll” Nemeth (bass, vocals), Billy Siegel (keys, vocals), and Dan Donovan (drums, percussion), the band embraces a true “no limits” approach to jamming, tapping into the cosmic spirit at the heart of their sound. Members of CJB have shared the stage with artists from legendary acts including Jerry Garcia Band, Talking Heads, RatDog, Hot Tuna, Parliament Funkadelic, and Dark Star Orchestra, among many others. Drawing from the Grateful Dead catalog and Jerry Garcia’s solo projects—while weaving in influences from Phish, Talking Heads, The Velvet Underground, and beyond—Cosmic Jerry Band delivers inventive setlists and electrifying performances that elevate vibrations, melt faces, and create a truly cosmic live experience.
