There is more than one artist with this name:
1) Red Horse is the Providence/Boston-based blistering free-post-everything project of drummer/multi-percussionist Eli Keszler and guitarist/mad-scientist Steve Pyne. While both musicians are active in a number of different projects, Red Horse catches them working with a distilled sense of focus and is for many their breakthrough project.
Garnishing Keszler’s well-worn patented hyperactive splatter-beats, Pyne experiments with a veritable arsenal of home made equipment – from gargantuan electrified, automated string sculptures to confusing sequences of reclaimed speakers (taken from a very well known Eastern-themed music box) wired together creating a wall of screaming feedback. In the wrong hands their sound could easily be stuffy and academic, but Red Horse inject their experiments with a punk spirit rarely heard in the avant garde.
2) Red Horse is a collaboration by independent folk singer-songwriters Eliza Gilkyson, John Gorka and Lucy Kaplansky. It is both the name of the studio album released by the trio on Red House Records in July 2010 and the name under which they have toured and performed in concert together as a folk / Americana supergroup.
