It feels odd to criticize an artist for being too intelligent or insightful, but avant-garde electronic music producer Terre Thaemlitz simply steps over the fine line between ideas that are sincerely engaging and those that come across as too self-consciously academic in their appeal for intellectual engagement. More aural concept art than music, the sounds on Interstices have an underlying theme that is undoubtedly well-conceived and equally conceptual; however, unless the listener treads through Thaemlitz's daunting ideologies (poorly annotated in the liner notes), the album's underlying conceptual foundation doesn't surface in a decipherable manner. In fact, anyone managing to wade through the exhaustive ideologies will still find it difficult to see how the sounds on this album relate. Ideas only go so far -- who honestly re-reads books for pleasure? Well, this album is about as fun to listen to as a philosophy textbook. There aren't really any melodies or rhythms but rather a continually streaming montage of musique concrète snippets that occasionally work but mostly seem like a lot of sounds sewn together in ill-considered fashion. Whether or not the listener subscribes to Thaemlitz's ideologies or his attempts to create aural concepts, it's still nearly impossible to enjoy this album as an experience worth returning to.
