Hey Rick, don't misunderstand me, I'm not trashing ELP at all, as a matter of fact it's one of my favourite bands.
All their stuff until Works I (except the Lake's side) is incredible, Their debut album is awesome, Tarkus is complex but amazing, Pictures is a masterpiece, Trilogy and Brain Salad Surgery are IMO in the top 10 prog' albums of history, and almost all their live albums are great.
I had the luck to see them twice, the first one in 1977 and the second time in 1995 and they still had the quality. Sadly none of their later releases has the level they achieved between 1970 and 1973.
