The debut album from Rainbow is every bit as good as the next 2 albums which for reasons unknown to me are always pronounced by critics to be much better than this one. Not the case. Dio's voice is on top form, with some slower numbers that highlight the beautiful tone and timbre of his voice not commonly heard on his Black Sabbath and Dio albums. Personal favourites include 'Catch the Rainbow' (better than 'Rainbow Eyes' from LLR), 'The Temple of the King' and of course 'Man on the Silver Mountain'. A must own for any lover of classic 70s rock and I can't for the life of me understand why this album is not hailed as classic of the genre. Everyone I know who loves rock loves this album. Can't think of a better first 3 albums from any rock band except maybe for Queen's first 3 albums. When I was a kid in the 80s (I'm 42 now) I favoured the Graham Bonnet and Joe Lynn Turner versions of Rainbow because I liked over-produced American-sounding rock. Can't believe I did because now the Dio albums still sound fresh whilst the later stuff sounds formulaic (though still good in its own right). Buy it!
