Me and wifeyface are listening the SHIT out of Flap! lately. Just my kind of thing. Bouncy, jazzy, funny, sweet. They were at the Edinburgh Fringe, and my parents really wanted me to see them as they'd seen them do a short set on an outside stage. I immediately bought two albums.
A bunch of my Norwegian friends make this sort of ramshackle semi-improvised folk music, and they just came out with a video, which I think you might enjoy. Done in one take! (And if you look closely, you can see the tablecloth catching on fire, only to be extinguished with champagne.)
