The band has been described as "a 21st century jam band, a 'Plastikman-meets-the-Grateful Dead' juggernaut." The band consists of Mathew Jonson, Danuel Tate, and Tyger Dhula. Together with regular collaborator The Mole (Colin de la Plante), the group has also performed as The Modern Deep Left Quartet.
