Ever since the premiere of his 'Untitled (How Does It Feel?)' video way back in 2000, D'Angelo turned into an enigma.

His breakout jazz and R&B album Voodoo was a critical and commercial success, but D'Angelo, born Michael Eugene Archer, lacked in any sort of follow-up. Eventually, after more than ten years, it became an almost forgone conclusion that Voodoo was the end of D'Angelo's short career.

That's why it was such a surprise when he, alongside The Roots figurehead ?uestlove, performed unannounced at last year's Bonnaroo Music Festival.

Directed by Danny Clinch, fans who missed the surprise showing now have a chance to take a more in depth look at what happened. Part one of the four part documentary features a lengthy "superjam" with ?uestlove's special band, performing Prince's 'My Summertime Thang' from his days with The Time.

The following pieces include performances of 'Getting The Band Back Together', multiple versions of 'Hit It And Quit It', and 'The Return of D'Angelo', with a special rendition of The Beatles' 'She Came In Through The Bathroom Window'.

Check out part one and two of the series below and stay tuned for the following parts of the documentary.
