Acclaimed Brooklyn rockers Grizzly Bear broke a three-year gap between albums with last year's beloved Shields. This fall, they will deepen the experience of that album with a double-disc, demo-packed expanded edition.

After a brief band hiatus following the promotion of 2009's Veckatimest, the quartet began sessions for Shields in Marfa, Texas, before ultimately moving back to the same Cape Cod property that gave 2006's sophomore album Yellow House its name. The band began to write and record more collaboratively than ever, while still maintaining the same densely produced, richly harmonic sound audiences had come to expect. Shields ultimately gave the band its highest U.S. chart placement at No. 7 on the Billboard 200, and landed high on critics' year-end best-of lists from Pitchfork to Rolling Stone.

Shields Expanded will feature an eight-track bonus disc featuring several of the tracks from the Marfa sessions that were ultimately shelved. (One of those, "Will Calls," is the lead single for the project and can be heard above.) Three remixes, including one released on a Record Store Day-exclusive single in 2013, will round out the package. Those who already bought the album can experience the tracks separately as Shields B-Sides, a separate 12" record to be released alongside the expanded set. (Shields B-Sides will include the five demos and B-sides, with the remixes offered as free digital downloads.)
