FOO FIGHTERS: SONIC HIGHWAYS episode 7: Dave Grohl, Butch Vig, James Brown. 

It's Friday, which means a new episode of Foo Fighters' HBO documentary Sonic Highways (chronicling the making of their album of the same name) will air tonight.

And with it comes a brand new Foos' track, "Congregation," the best song we've heard from the new album so far. Featuring Zac Brown, this track was recorded in Nashville's Southern Ground studio and inspired by the city's musical history. Each song on Sonic Highways was recorded in/inspired by a different city with a rich musical history.

But despite the Brown/Nashville connection, "Congregation" is less country and more '70s classic rock -- this is the sound of souped-up car racing down the open highway. Listen below.
