Circulatory System

The Profile

Circulatory System is an American psychedelic/indie rock group formed by Will Cullen Hart after the breakup of The Olivia Tremor Control, part of the Elephant 6 collective. Their 2001 self‑titled debut blended home 4‑track recordings and studio sessions, with contributions from Elephant 6 peers including Jeff Mangum and Jeremy Barnes (Neutral Milk Hotel), Julian Koster, Eric Harris, and John Fernandes.

Originating from the Elephant 6 scene after The Olivia Tremor Control split, Circulatory System debuted in 2001 with a self‑titled album that extends OTC’s psychedelic pop ethos. The project centers on Will Cullen Hart and features collaborations from fellow Elephant 6 musicians such as Jeff Mangum, Jeremy Barnes, Julian Koster, Eric Harris, and John Fernandes.

Circulatory System is presented as Will Cullen Hart’s post‑Olivia Tremor Control project, rooted in the Elephant 6 collective. The 2001 self‑titled debut is framed as a spiritual sequel to Dusk at Cubist Castle and Black Foliage, blending pop craft and psychedelia. The album spans 22 tracks over 58 minutes, mixing 4‑track home recordings with studio sessions. Contributions include Jeff Mangum, Jeremy Barnes, Julian Koster, Eric Harris, and John Fernandes.
