Yet another highlight from the 2015 Fretboard Summit: Blake Mills inviting Bill Frisell onstage to perform this cover of “Blood in My Eyes.” The tune, originally recorded by the Mississippi Sheiks, appeared on Bob Dylan’s 1993 World Gone Wrong album.

Prior to this song, Frisell and Mills had never performed together. It was one of those rare, only-at-the-Summit moments.
