I think Libertad's pretty good but honestly Weiland's the only part of it that keeps interest. I've always hated Sorum, Duff is hit or miss, Slash is great but predictable, and really Dave's the only instrumentalist in the band that comes up with things I don't feel like I've heard a million times before. If Slash would be the blues rock guitar player who now and again experiments with say jazz chords or more interesting sonic effects I'd be much more impressed.
Really the second I found out I felt this way was when I heard the cover of "Psycho Killer" and of COURSE it was a blues version of the song. C'mon Slash, you took a new wave song and made it classic rock. How original of a take is that? Weiland shined though.
