Foo Fighters' new album Concrete And Gold features some very surprising collaborations, one of which includes a track with contributions from one of the kings of pop himself: Justin Timberlake.

The product of the union, “Make It Right,” is a grungy wild child of a track, featuring the ex-*NSYNC crooner.

Timberlake lends backing vocals and some very distinctive “la la las” to the song. You can hear them about halfway through during a crescendoing bridge, which Dave Grohl has nothing but the highest of praise for.

How exactly did Timberlake and Grohl cross paths? The pair often hung out between takes at EastWest Studios in Los Angeles. “We’d drink whiskey in the parking lot,” Grohl explained during an interview with Rolling Stone. “He was really, really cool. Then the night before his last day, he says, ‘Can I sing on your record? I don’t want to push it, but – I just want to be able to tell my friends.'”

Grohl previously teased contributions to the album from the “biggest pop star in the world” during an interview with BBC Radio 1 back in June. Timberlake is hardly the biggest name on the album, however, with Sir Paul McCartney, Boyz II Men's Shawn Stockman and Alison Mossheart of the Kills joining in on the party.

Grohl has been on a press tour circuit lately promoting the new album and recently sat down with Metallica's Lars Ulrich to chat about Concrete And Gold, the songwriting process and more. You can check out the full interview below.
