I saw the 2nd half of their set, and it was good. I was right up front, so I could enjoy it. I saw him at Barbes a few years ago and have been wanting to get back. He didn't have the washboard player with him this time. It was a bass player and another guitar. It was very good and a great opener.
Wrembel plays in the style of Django Rheinhartd and he's great. He usually plays every Sunday at Barbes and it's very much worth getting to.
He mentioned that a great Django style player is coming from France on 1/23 to Joe's Pub and he doesn't record. This would be a great time to see him. I will be out of town, but I would consider it otherwise.
