Dave solo are mediocre at best but once he has a band to jam with there really is no one better. I can't figure it out...ever solo I head him do he just seems like he has no idea what he's wants to do but my god once he jamming with other guys he's a genius. So weird.
Maybe it's just me but Dave, aside from his work with Slayer and other thrash metal giants, should not play solos. The impression is he's hitting randomly without any logic. I think he sould play some songs, where at hid best, and don't play solos where he's at his worst. I'm not very in with drum solos, I think only a few drummers can afford to play them. And, to me, Dave is one of the worst among pros when soloing.
