The thing about Eddie and Hendrix...they had technique/technical ability, but it's still their songs that resonate.
Randy Rhoads was a fine player. If I'm being frank, I really didn't much care for the tunes he was coming up with when he was in Quiet Riot, thus while I still think those first two Ozzy solo albums are fantastic no small part of that probably included what Daisley was contributing as well. But...yeah, even though Rhoads had kicked around for several years with Quiet Riot then a couple with Ozzy, it still felt like he was just getting started when he died in terms of realizing his potential. Rhoads, along with Van Halen, certainly demonstrated in the early 1980s that rock guitar didn't have to be endless blues pentatonic scales.
