A celebration of the rewards and challenges of dedicating one’s life to playing and mastering a musical instrument. Part one opens with narrated behind the scenes footage featuring discussion of the love of playing music and the lifelong relationship with an instrument, and detailing the process and challenges of recording and filming this unique performance, then segues to part two, in which Grohl performs the titular 23-minute, one-man-band instrumental recording on which Grohl plays all seven instruments on the track, all live.
