Properly constructing a box set is a daunting task. Most failed box sets mix hits and hit-and-miss rarities, so that neither fans (who own most of the material) or casual fans (who just want the hits) are satisfied with it. When Not Lame Records assembled a Posies box set, the label issued a limited-edition run (2,500 copies) including nothing but unreleased material. The four-disc, 66-song At Least, At Last: Demos, Live Recordings, and Whatnot 1987 to 1998 is a fan's dream, with demo versions of nearly all of the band's hits and many album tracks with superb sound quality, despite their demo status. There's a handful of live tracks, including Ken Stringfellow and Jon Auer's first performance as the Posies, and a handful of unreleased tracks, including covers (Blondie's "Dreaming," Devo's "Wiggly World," Cheap Trick's "Surrender," and Big Star's "What's Going Ahn"), that were intended for never-released tribute albums. Great works-in-progress abound, including two early versions of "Apology" -- seen in different stages of development -- and a demo of "Oh Michael," a song with a melody later assimilated into Swirl 360's "Ask Anybody." Muzak versions of "Golden Blunders" and "Suddenly Mary," two of the band's early hits, complete the set; it also includes a full-color book with liner notes from Stringfellow and Auer themselves. At Least, At Last is a complete retrospective and a last, personal look one of the driving forces of '90s power pop (along with Matthew Sweet and Teenage Fanclub). It's a peek inside the studio before glossy production was laid over many of these tracks, and that's what makes it an effective and stellar box set -- almost four hours of intimate, rare music that fanatics of the band will go wild over.
