Welcome to #TBT Mixtape, Billboard's series that showcases artists' very own throwback-themed playlists exclusive to Billboard's Spotify account. The curated set features the artists' favorite tracks from their youth and childhood.
This week's spin comes from Peter Bjorn and John. The Swedish trio -- comprised of members Peter Morén, Björn Yttling and John Eriksson -- formed in Stockholm back in 1999, with a handful of early '00s albums making waves in Europe. But it wasn't until 2007's Writer's Block -- their third LP -- that they achieved global stardom, thanks to the set's first single "Young Folks," whose famed whistling earned it widespread critical praise and the band slots performing on The Tonight Show With Jay Leno and Late Night With Conan O'Brien.
A decade (and four more LPs) later into their lengthy discography, the seasoned vets returned last week (Oct. 19) with the release of their eighth proper album Darker Days, released via INGRID. To fete the career milestone, the indie titans are looking back to their youth as musicians growing up in Sweden, with three separate playlists to comprise this week's #TBT Mixtape.
