Grizzly Bear will be following up the critically acclaimed album Yellow House in 2009 with a new album due out late Spring. Stateside success has already involved appearances on David Letterman and Conan O'Brien and with the Los Angeles Philharmonic Orchestra, being handpicked by Paul Simon for an intimate hometown show in Brooklyn, and a US support tour with Radiohead punctuated by a public declaration of love from Johnny Greenwood who said in front of a large audience "Grizzly Bear are my favourite band".
