In this animated version of Jimi Hendrix's lost final interview, he calls himself a mad scientist, talks about the place of fantasy in his music, and expounds on his favorite saying: "When things get too heavy just call me helium, the lightest known gas to man."

The interview took place in London with Keith Altham in 1970, a week before Hendrix's death, but was only broadcast this year. PBS Digital's Blank on Blank, which unearths old sound files and pairs them with new animation, put together this new animation.
