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.

It's encouraging that nearly four decades into one of the most impressive careers in indie rock, Yo La Tengo are still finding new ways of doing things. On 2018's There's A Riot Going On, the band upended their usual process of writing material and then re-creating it in the studio by setting up recording gear in their rehearsal space and capturing their music in a freer and more spontaneous manner. For that album, YLT handed the tracks over to John McEntire (of Tortoise and the Sea and Cake) for mixing, but 2023's This Stupid World sees them cutting out the last middleman in their process – this time, the band mixed the tracks themselves, and for the first time they've made an album with essentially no outside input.

New Jersey indie rockers Yo La Tengo had already been slowly growing into their sound for over a decade by the 1997 release of their revelational eighth album, I Can Hear the Heart Beating as One. Their guitar-based pop was steadily finding its legs before this, as the band moved toward increasingly dreamy productions on albums like Painful and Electr-O-Pura. The 16 tracks that made up the ambitious and epic I Can Hear the Heart found the group stretching out their whispery vocals and deceptively straightforward pop approach to encompass a variety of unexpected styles. This meant softly wandering guitars and steadfast drums twisted out of their indie rock trappings and morphed into adventurous Krautrock jams like "Spec Bebop," haunting, harmony-driven psych-folk like "We're an American Band," and even a playfully naive take on bossa nova with "Center of Gravity." As for the blissed-out melodic noise pop Yo La Tengo had been working on for the majority of their existence, this was one of the band's finest hours.
