By 1999, Basement Jaxx was in full swing. After five years in house music’s trenches, the London producers had emerged with a debut album, Remedy, that crossed far beyond clubland. As quickly as dance and pop mutated and hybridized across the following decade, the duo seemed determined to explore every possible avenue: funk, hip-hop, disco, 2-step, and even punky shout-along choruses. Commissioning audacious, wide-ranging remixes was just one more way of satisfying their curiosity, and extending their sound as far as it could travel. There’s plenty of straight-up house music here: Lil’ Louis, Armand Van Helden, and Erick Morillo & Harry ‘Choo Choo’ Romero all deliver chunky, big-room mixes infused with the spirit of the ’90s. But Lost Remixes is also a history of the decade’s shifting trends, like Switch’s fidget house, Floating Points’ boogie, and Dem 2’s slinky UK garage. Vitalic turns the Siouxsie-fronted “Cish Cash” into chilly electroclash; Dillinja flips a poppy Dizzee Rascal feature into a double-barreled blast of weaponized breaks and ray-gun bass. There’s even a dubstep remix of “Raindrops” from Joker & Ginz, a flashback to the moment when the sound called “purple” was infusing dubstep, normally quite serious, with a healthy dose of funk and humor. (No wonder Basement Jaxx approved.) What’s clear is Basement Jaxx’s knack for choosing remixers whose music exudes personality; what’s remarkable is that no matter the style of the rework, the duo’s own spirit radiates out from the center, inextinguishable.
