I'd seen Marc Maron live before, and am a regular listener to his WTF podcast so I had an idea of what to expect going in. There were plenty of laugh-out-loud moments, quite a few chuckles but also a lot of dead time or some moments that were mildly amusing, but not really hilarious. Maron made a point of saying that he didn't prepare for the show, which I thought was schtick, but appeared to be the truth later on as he debated with himself about which bit to do or which direction to take the show.
Some of Maron's self-analysis is interesting and humorous and is something you don't see a lot of performers do, but I do have to confess to being a bit disappointed that he wasn't sharper or funnier. He also told several jokes/stories that I'd heard him do on his podcast before, which was a bit of a letdown since I knew the punchlines ahead of time. Part of why I like to see performers live is that I get a chance to see them perform material I haven't seen or heard before.
All in all, this was a good performance but not a great one. I'd still see Maron again but will hope next time he does newer material.
