I Love Star Wars, but I Don't Like TV Shows

Po Ocalypse is one of many sci-fi series that have been inspired by pop culture. The writers often use a gimmick to make the audience look back in time, rather than just looking at what's happening now. In this episode they bring forward great musicians from the past who weren't featured in previous films. They actually subvert this trope by getting some one past us who does "some weird aetonal thing" and playing himself.
