An old demoscener wrote some Swedish articles about C64-music as a university project. (Read here).
(my translation) “There’s a couple of bands that perform C64-songs with traditional instruments live. SID80’s, Press play on tape, Goto80, The C64 mafia and the acapella group Visa Röster are some of the names.” Yikes. C64-remixing isn’t really my thing, eventhough it has happened once or twice or thrice or thrhurrhhaiejg.
