Query: Tarkus is excellent but not consistent.

Tarkus has been around a long time but it deserves a listen even today because ELP did some things on it that no other band has really attempted. The album does suffer today because so much has happened in synthesizer, drum and guitar technology but the whole conception of Tarkus and its implementation make it seem like it was made yesterday. The strength of the album is the music fitting into an apocalyptic conception which is rendered through music, like War of the Worlds. Yes tried similar conceptions though never with so much success musically. Tarkus was one of ELP's best albums and it grows on you.
