Scott Weiland’s skills as a rock star are extremely underrated, in part because his long, public battle with drugs and notorious unreliable behavior has eclipsed his musical output in the public eye. So it’s a bummer to see Weiland moaning and slurring his way through Stone Temple Pilots’ “Vasoline” at his band the Wildabouts’ recent Corpus Christi gig. Weiland’s rep told TMZ drugs were not involved in the messy performance and that it was a “perfect storm” of fatigue, a malfunctioning monitor system, and a couple drinks before the show. Watch below, and prepare to cringe.
