Crazy review there. I wouldn't even say Matt was drunk, maybe buzzed a bit. I've seen him downright wasted and he was coherant throughout the night in my opinion. Vanderlyle was actually a highlight for me and calling Mr. November their best song is criminal.
Also regarding Matt and his drinking. It's way better than Matt sober and nervous. The BAM show that streamed earlier this year is a prime example. Matt didn't seem to drink at all and was so restrained it was one of the must stuffy and mediocre sets I have ever seen them perform.
