Also surprised TAC hasn't fellated something to do with Schenker in this thread. At least he's smart enough not to make a homer pick like Alice Cooper.
For me personally, I could definitely put Michael Schenker's first 4 albums.
Technically, the Alice Cooper band's first two albums were Easy Action and Pretties For You. They are fairly obscure. If I didn't have to count those, the initial Warner Bros run of Love It To Death-Killer-School's Out-Billion Dollar Babies is exceptional. The most underrated American Classic Rock band.
I have the same issue with UFO. They had two very obscure albums before Schenker joined, but again, if I didn't have to include those, the initial Chrysalis run of Phenomenon-Force It-No Heavy Petting-Lights Out would rule.
