One of the original innovators in the ambient/trip-hop movement, Tranquility Bass' Mike Kandel submerged for most of the '90s before finally issuing his debut album in 1997. Kandel grew up in Chicago but moved to Los Angeles in the early '90s; inspired by his hometown's acid-house ideals, he formed the Exist Dance label in 1991 with Tom Chasteen and began producing classic ambient-house singles like "They Came in Peace" and "Mya Yadana" (from the influential first volume of the Excursions in Ambience series).
