Foo Fighters is continuing to roll out new music from its forthcoming album Sonic Highways. Ahead of the fourth episode of the band's HBO series of the same name, today (Nov. 7), Dave Grohl and co. released the Austin-inspired track, the double sided "What Did I Do/God As My Witness" featuring Gary Clark Jr.

"What Did I Do/God As My Witness" begins with a short, snippy explosion of guitars. All at once, it sounds like a beginning and an ending as the blast of music sets the scene. After a short moment of silence, Grohl comes in unaccompanied, "There you go again, putting words into my mouth / This one's for you to know and for me to find out," he sings eventually backed by twinges of piano.

The song is thus far unlike anything else in Foo Fighters' discography. It's a bit theatrical, with plenty of starts and stops in the first half "What Did I Do," clearly pulling in the influence of the southern city Austin.

During the "God As My Witness" half of the track, there's a more distinctive Foo sound. "God as my witness / Yeah, it's going to heal my soul tonight," Grohl croons in the slowed down jam with a notable scratch and growl in his voice. This recalls some of the slower yet still more epic sounds of the Foo Fighters discography, bringing the song home with a strong note.
