This record reunited Ritchie Blackmore and Ian Gillan, and the finished product is by far the finest work by this band. Musically, Ritchie was hitting everything, by far his best since Rainbow. Ian was in top form, just after departing Black Sabbath after one album. The solos were tight, the vocals sounded like Ian back in the 70’s. The rhythm section of Glover, Paice, and Lord was second to none. People will think Machine Head was their shining moment, but one listen to this and I guarantee you will shake your head with amazement.
