Saw STP live a couple years ago when they reunited, and they were surprisingly good. I'd heard stories of how they sucked lived, but they killed that night. Tons of energy, and played all their best stuff to perfection.
AIC last album lacked in two areas for me, inspired song writting (some of the lyrics and melodies were painfully bad), and their signature rhythms. As bass player I admire Mike Inez, but he and the drummer mailed in their performances. Instead of their simple groove with a hint of tribal-esque. beats they played straight boring rhythms. It just wasn't AIC for me.
