Newly instated into the rotation of KEXP's long-running Expansions program, techno/house DJ/producer Hanssen has garnered yet one more impressive achievement in a career that dates back to the late 1990s with the great left-field house duo Jacob London. For decades prior to this promotion, Hanssen has been spinning engrossing sets in area clubs and producing a body of work that encompasses kosmische ambient and playful, melodious tech-house for labels such as Hush Hush, Pleasure Boat, and Innerflight. This is a rare chance to experience a master of underground dance music do her transcendent thing. by Dave Segal
