There are few albums by The Rolling Stones that are as controversial as this album. It is radically different from anything the Stones did before, or after and has divided fans into two camps: those who love it and those who hate it. I, personally, love it.
It is often described as a poor attempt to copy The Beatles' Sgt Pepper. But, having spent many hours comparing the two albums, (Hours I could have used doing something beneficial with my life) I think the two are very different albums. If it were to be considered a rip off of any Beatles album, it would be Magical Mystery Tour. But, seeing as the two albums were released at around the same time, I don't think that's likely.
The album varies from the child-like 'She's A Rainbow', to the disturbing space rock of '2000 Light Years From Home', from the hard guitar driven 'Citadel', to the whimsical country style 'Gomper'.
It is an album that can only be made with an excess of drugs, happiness and studio time, and is definitely worth listening to, if you are a fan of psychedelic rock or The Rolling Stones. Even if it is to see what all the fuss is about. I can't say whether you will like it or not, but I can say with almost certainty that you will not forget about it anytime soon.
