Yes, despite it being Procol Harum's worst selling album (released at the heigt of punk rock), it really is quite good. It was also pilloried at the time for the second side of the original album, which comprised just the one complex piece "The Worm & The Tree".
However, despite some embarrassing moments (the narration and the fable are not high points), some of the actual music of "The Worm & The Tree" is very pretty and certainly on a par with some of Procol's finest.
The first side of the album is also strong with some very beautiful melodic pieces such as "Skating on Thin Ice" and "Strangers in Space". Contrasting with these are the title track and "The Mark of the Claw", written by then current guitarist Mick Grabham, which are beefier and more up tempo.
All in all, I would have thought that most fans of Procol Harum's would enjoy this album: even those fans who may have been disenchanted with a couple of their previous offerings, as in my opinion this album is better than, say, Procol's Ninth.
Of the bonus tracks, "Wizzard man" is very catchy and well worth having on the CD.
Good sound quality too.
So, if you have often thought this was "procol's Turkey" then think again and give it a chance.
