It’s been a guest-filled summer for Foo Fighters and that continued on Friday night in Phoenix as the band welcomed out new friend Jewel to take lead vocals on Led Zeppelin’s “Whole Lotta Love.” Grohl recounted first meeting the singer before inviting her out on stage to handle Robert Plant’s vocals.

As they did the previous night in Los Angeles, Gary Clark Jr. once again joined the band for “What Did I Do?/God As My Witness,” the same song he played on during the band’s Sonic Highways recording session that also resulted in an HBO series of the same name.

Next up for the Foos is a show tonight in Albuquerque, NM.
