You know that scene in Barbie in the Diamond Castle at the start of the movie where their playing their guitars and singing? I'm getting very similar vibes watching it and it's great 😅
You should also try some Deftones or TOOL covers maybe. Not sure quite how hard it would be, I enjoy both of those bands because they incorporate so much creativity, which would probably make it more difficult to play. But oh my god both of those bands have made some of the best music I have ever heard.
