Over all, the whole phenomena of ELP was a fever that took too long to run its course, but for all their mechanical onanism, they did at times amuse me or impress me to an extent. Tarkus, their 1971 studio album, was such an extreme example of unplayable , undanceable, unlistenable, jig-sawing time signatures that I wound up respecting it as something wherein we have a band that accomplished exactly what they set out to do, produce a loud, grinding, smoke and spark belching bit of unlovable Avant Gard music. I would assert that if a college music department had their resident experimental music ensemble take up this album as a proposed project in search of some grant money, it would come pouring it.
That is say that it's very unloveability fits right in with much more contemporary noise makers at the edges of listenability. Also, these fellows had the the chutzpah to take Copeland's sacrosanct "Hoe Down" and turn it into a keyboard dominated speed metal blitz. I loved that.
