-- Grizzly Bear have unleashed a second track from their upcoming 'Shields' album, which drops Sept. 18. Not surprisingly, 'Yet Again' is another gorgeously textured tune -- but this time around comes with a dynamic boost in the form of a hot little rocking riff at the end. Nice! [Spinner]

-- Speaking of new bear tracks, fellow New Yorkers Bear In Heaven have issued a download of the latest single from their 'I Love You, It’s Cool' album, titled 'Kiss Me Crazy.' [Death + Taxes]

-- Silversun Pickups have announced dates for a fall North American tour that kicks off Sept. 1 in Calgary, Alberta and is scheduled through a Sept. 21 gig in Chicago, Ill. They also will rock New Orleans' annual Voodoo Music Fest on Oct. 26. [Tiny Mix Tapes]

-- Ready for another new track? Bob Dylan, the original rock 'n' roll rebel, has premiered a new one called 'Early Roman Kings' from his 'Tempest' album, out Sept. 11. [Ultimate Classic Rock]

-- Meanwhile, the release date for Muse's own new album, 'The Second Law,' has been pushed from Sept. 18 all the way back to Oct. 2. It's been pointed out that the original date was a crowded one, with new discs from the Killers, Band of Horses and several other bands also due that day, but we like to call such people conspiracy theorists.
