Hanneman and Lombardo have influenced me the most as a musician, but their absence does not make Slayer a "karaoke band".
Let's face it, most people see King and Tom as the main dudes. I mean, you've got the singer and the dude who plays the solos.
If Hanneman and Lombardo kicked out King and Araya, then yeah, it'd be a karaoke band.
You're absolutely wrong.
Every member of Slayer has always, and will always, be as important as any other.
Dave is by far one of, if not THE best, drummer in Thrash, and probably in metal, period.
Jeff was always just as important as Kerry onstage, the fans know that. He just didn't deal with much media.
If anything, Tom is the lowest profile guy, and he's THE FACE of the band.
Kerry is the media figure, but to the fans, they know what Slayer really is.
