‘Thank You Caroline’ has history in The Avalanches’ relatively slender catalogue. The B-side to the Melbourne sampling whizz kids’ very first single (1997’s flute-laced Beastie Boys/J-Pop mash-up ‘Rock City), it’s a slightly woozy, organ-dominated instrumental that lulls listeners into a world of elevator music before pulling the rug on that notion, thanks to its layered keys and great freestyling solos. The most significant comes from saxophonist Mark Ford, although it’s so cleverly treated it’s hard to tell it’s a sax. A lazy earworm that reveals more with every play, ‘Thank You Caroline’ feels like a shift from their established modus operandi – played not sampled. The song enjoyed a second B-side life when Andy Votel remixed it for the flip of 2000’s ‘Since I Left You’. He drilled down deeper into its essential otherness, separating the layers even more and adding more sinister elements (a music box-sounding xylophone, cellos, humming, acoustic guitar) to effectively create a new track. A third version of this B-side – an original demo, even further removed – surfaced on 2021’s reissue of the Since I Left You LP, itself a supernatural sampling feat that artfully reanimated over 3,500 vinyl cues.
