Jack White brought Black Crowes frontman Chris Robinson on stage during a Chicago show to cover Free’s “I’m A Mover”. The collaboration stood out because it paired White’s guitar-led performance with Robinson’s vocals, and White later shared footage despite the concert’s no-phones policy.

The performance took place at Radius on Thursday night during White’s tour supporting his new album, Frozen Charlotte. Rather than choose one of Free’s best-known songs, they performed the relatively deep cut from the British band’s 1969 debut album, Tons Of Sobs; the article describes their rendition as fast, flamboyant and energetic.
