Ritchie Blackmore was important. But from my point of view Jon Lord was more important than Ritchie Blackmore. Cause Ritchie Blackmore was kinda a pop guitarist. When Jon Lord was more interested in metal music. Though both of them were classical inspired musician, but I saw in a documentary that he got the idea first. - zxm
He deserves the second or first place on the list. If he had played guitar then people would give him credit. Not only he is the inventor of metal but also one of the pioneers of organ solos. He didn't like organ players only playing organ in back. - zxm

Only brought darkness to metal. That's it. (Though Ronnie James Dio also wrote some dark lyrics). He never sounded like a metal singer to me. I don't remember much metal singers who were inspired by this guy. Even singers like Robert Plant (Rob Halford) or Elvis Presley (Ian Gillan) were more influential than Ozzy Osbourne. - zxm
