New York act Grizzly Bear are set to embark on their first major US tour in support of Yellow House, their Warp Records debut. Recently, the band handled opening duties for the sold out TV On The Radio tour, in addition to three successful European jaunts. This tour kicks off in Philadelphia on February 1 and wraps up in New York on March 6 at the Bowery Ballroom. Fellow NY band Dirty Projectors and SF’s Papercuts will be support for a majority of the dates.
