The Avalanches release “Blue Shadows,” a new collaborative single featuring Karen O of Yeah Yeah Yeahs. Multiple outlets report the track appears after a run of recent releases tied to the band’s ongoing activity, including earlier collaborative songs. Stereogum notes the group has recently teased a new album while also issuing singles with other artists, and says “Blue Shadows” is accompanied by a posted video. NME describes the song’s character as “achingly forlorn,” and reports that the group says it “somehow sounds as if it always existed.” The outlets frame the collaboration as part of the band’s broader approach to pairing with contemporary artists, with Karen O providing vocals on the track. While descriptions of the song’s mood differ in wording, both sources present the same core information: “Blue Shadows” is a new Avalanches single released with Karen O and made available to listeners through a digital posting, including video content. The band continues to build anticipation around its next album while sharing additional standalone releases.
