Wildflower is the second studio album by Australian electronic music group the Avalanches. It was first released on 1 July 2016 through Modular Recordings, Astralwerks, XL Recordings, and EMI. Production lasted 16 years and began around the release of their debut album, Since I Left You (2000). Pat Shannahan reckons around 50 samples were cleared for Wildflower commencing in 2012. The album contains 21 tracks and features multiple collaborators. The album was formally announced on 2 June 2016 alongside the release of its first single, an extended mix of "Frankie Sinatra". After the release of Since I Left You in 2000, the Avalanches continued to produce music. Over the course of a decade, the group worked on a wide variety of projects which involved collaborations with multiple artists. The album began as "ambient world music", and by early 2007, the band was considering over 40 tracks for an album which had become mostly hip hop oriented. The group became more involved in separate projects which pulled them away from the album. Some of their most time-consuming work included the score to a musical, King Kong (2013), and an animated musical film described as a "hip hop version of Yellow Submarine" which lost funding and was never completed. Wildflower features many remnants from these projects, but the Avalanches had to leave out many tracks which did not fit with the theme of the album. They plan to release these tracks at a later date. User-contributed text is available u
