I don't know anything about Flying Lotus and slightly more about Nardwuar, but there's something infectious about this video.
FlyLo's kind of an underground legend in the electronic and hip-hop communities, he's getting popular now because he just dropped an album. He's had a lot of incredible artwork influenced by psychedelia and psychedelic culture from major artists too, so there's this whole modern scene of art, fashion, and music following this guy around waiting for him to drop a new beat. I suggest this very interesting album review for the new record, which definitely isn't his best (my personal vote is the Cosmogramma album). Basically, you may not dig his style or genre, but the rhythms he creates are honestly unrivaled at the moment, and keeping jazz as his main inspiration makes him that much more respectable imo. (Also the fact that he's directly fucking related to John fucking Coltrane.)
