This Heat is one of those forgotten bands from the late 70s/early 80s. They weren't popular at all because their music was everything but easy listening. And it's hard to describe their music. Pitchfork once wrote about them:
This Heat's sound was something like a confrontation of prog, free-jazz and contemporary electronic music (think early Stockhausen, not Kraftwerk). They often get lumped into the post-punk (or even just "punk") camp, for no better reason other than they started at the same time. They certainly sounded as if they were angry about something, and taking a glance at the lyric sheet for this album (and you'd better, as often the vocals seem more musical element than communicative force), they had fairly intense political/social statements to make-- though pinning down their position is often as hard as pinning down their sound. In any case, they were "progressive" in the literal sense of the word, and though they came up with the first wave of punk, they didn't really sound like anyone else of the time (save a few other English radicals like Henry Cow or Art Bears, occasionally).
Sure, some kind of music that may hurt. But didn't the Frank Zappa or Captain Beefheart hurt us as well?
