I think to say McCartney is great and Gene sucks is just stupidity. Technically, neither is amazing, but both play clever, melodic bass lines. Gene does it in a Monster costume and high heels also. I've met so many bass and guitar players who CAN'T play Kiss riffs very well at all, and talk about how bad they are. The Bass solo in the Kiss show is for Gene to spit blood. Don't be a jackazz and act like he fails to be Jaco. How come Jaco didn't spit blood in his solo? Stupid, right? You got to put it all in context. Kiss is an entertainment machine. They also have TONS of great hard rock tunes. So many other rock bands are considered incredible and there tunes are so basic also, and in most cases, directly inspired by Kiss. If you hate Gene, great. I love hearing it. It IS a forum and there will be those that attack. I do it myself. When I think of the Beatles, for example, I think of vocal melodies and accompanying chording. Not reallly a riffing band. Kiss is far more riff oriented. They have huge rock riffs. The bass playing in both bands is very similar, unless you are deaf. But check out some great Kiss riffs and the bass that goes with them, ie "Watchin' You", "Goin' Blind", "Deuce", "Black Diamond", "Parasite", "Strutter", "She", "Two Timer", "Sweet Pain", etc, etc.
However, it would have been very cool to see Jaco blow fire and fly with blood all over his Jazz bass.....
