I love love love love love this show. It's so friggin' good so quickly. I don't think it's a surprise if you've ever met Brett -- dude works his ass off and commits to his bits and characters harder than anyone ever has.
If you ever get a chance to see Brett's movie Bananazzz (starring his punk poet hero Craig Evanhalen), do so. It's ridiculously funny and smart.
There's a whole crew of folks in NYC now coming up who are really pushing things creatively. A semi-regular on his show is Jo Firestone. She's starting to get a ton of press (like four things this week alone) and deservedly so. She does some of the most imaginative comedy (include setting up a stand-up show for dolls) out there.
This whole scene has constant shows. I know I'm namedropping my brother here but I am sure he will be fine if I tell you that they're his favorite shows to both perform at and even just watch. I feel like I have to up the weirdo game in Philly because of these young bucks.
