Their first 3 albums were great and never got the attention they deserved. I love their Perry albums, too, though.
Much of the blame can be laid at the feet of radio stations and their formulaic playlists. I even badgered our local "classic" rock station to play some real classic rock (i.e. early Journey), but to no avail.
People always love the early stuff when they hear it, though, and not many people have heard it..
Some of the Perry stuff is ok, but it's just been played to death.
