The Cybertronic Spree, a Transformers-themed band with sweet costumes and I presume at least an awareness of the band The Polyphonic Spree, specializes in covers of cartoon and video game theme songs. Except for this one time where they decided to cover Led Zeppelin's "Immigrant Song," because why not? It's a fun song, everyone knows it and they're clearly capable of playing it.
