It's hard to believe sometimes that Spring Heel Jack used to make drum 'n' bass and performed at raves. For some time now they've been working in free jazz and electro-acoustic circles, and are decidedly dance-floor-unfriendly these days. That's not a bad thing, as they brought dance music's knack for making the abstract musical into their avant-garde explorations. It's difficult music, to be sure, but evocative and pretty in its own weird way. The electronic interventions have faded further into the background here than in previous releases, and The Sweetness sounds more live overall, probably the result of recording right after their 2003 tour.
