What’s Up Matador is a 2-CD (or 2-LP) compilation that was released by Matador Records that chronicles some of the best artists within their roster during the 90s. The first disc serves as a bit of a “best of” collection, featuring indie standouts by Yo La Tango, Pizzicato Five, Cat Power, Helium, and of course, Liz Phair. The second disc is what is particularly noteworthy, as it features previously unreleased material from many of the same artists. This marks the official debut of Liz’s “Stuck On An Island,” a b-side that fans would later discover was in the initial running for whitechocolatespaceegg.
