The Police’s final albumSynchronicity is getting the deluxe anniversary box set treatment for its 40th anniversary. It’ll include a bunch of previously unreleased tracks — a rarity for the band, who haven’t put out a lot of early versions. The most exhaustive 4xLP will feature a remastered version of the original album, a collection of contemporaneous B-sides and bonus tracks, and two discs worth of unreleased alternate takes, outtakes, and instrumentals.
