Proggy warriors Yeasayer spent much of the past year recording the follow up to All Hour Cymbals. The first tune to hit the Inter-streets is “Ambling Alp,” which, if you try to say it five times fast, will have your tongue wrapped around your hangy ball. Not to be confused with a nut, your hangy ball will, in turn, be triggering samples on the MPC in your tonsils. Ok, enough dental imagery.  As is usually the case with Yeasayer, “Ambling Alp” is a worldly, tripped out affair unafraid of twisting itself up in all sorts of sound found hieroglyphics and Aboriginal beats. Oh, now you wanna hear it? Well, in order to do that you gotta sign up for the Yeasayer Clinic’s Free Dental Service, aka their list serv, through which an exclusive MPEG-1 Audio Layer 3 will be delivered to your inbox. Brilliant! Peep Yeasayer’s new alliteration of a web site for more info on the limited edition 12″ single, super heady tri-color T-shirt and some other new Yeasayer swag.
