I disagree with the view that Rising is Rainbow's best release: LLR&R is far better!
Dio's voice is superb, Blackmore's guitar excites and the late Cozy Powell is as solid and rocky as the Himalayas. A favourite balls-out moment is the fabulously frenetic guitar solo and accompanying double bass drums and fills in Kill The King (winner of 'most exciting axe solo' on the album for my money).
There are no bad tracks at all on this album (which can't be said for Rising: Tarot Woman, Run With The Wolf and Do You Close your Eyes are all turgid and stodgy to my ears - only Starstruck and Stargazer really cut the mustard, tho' Light In The Black's okay, I guess). Even the weaker moments of LLR&R are damn good by anyone's standards: The Shed and Sensitive to Light ain't Rainbow's best, but they still rock righteously enough.
Blackmore's penchant for medieval tom-foolery rears it's head on the beautifully mellow (they use recorders for Christ's sake!) Rainbow Eyes, which Dio sings exquisitely.
Truly their finest hour, and a classic taste of heavy rock at it's best...
