Play videoThe May lineup for the "Late Show With David Letterman" includes stops by Animal Collective on May 7 and Grizzly Bear on May 20. The two experimental and pioneering pop acts already have this year's two most talked about and lauded albums in Merriweather Post Pavillion and Veckatimest. Last time Grizzly Bear stopped by the "Late Show," the band made waves with the premiere of "Two Weeks" from Veckatimest. The album, due out May 26, is also getting some paper press: the New Yorker and New York Magazine.
