When is a band not a band? Bergheim 34 challenges the listener to answer that question as its four members-MS20 XXL, Steffen Neuert, Andrew Pekler (a.k.a. Sad Rockets) and Ann Vortisch-release a rich collaborative work that rarely saw any of them in the same room during production. Instead, the quartet relies on an iterative process of trading files and hard drives. The result is a brilliant m?lange of Herbert-esque blips and witty orchestration, with Vortisch's cool voice grounding productions that channel Art of Noise and '80s video games. Despite the amount of human input, there's a refreshing notion of gremlins at work here.
