Is rock dead?

Honestly if youre talking about rock like the music that used to get made and sounds the way it does then yes it's dead but that's good. Music styles, tastes, and trends evolve over time and it would be bad if it didnt because then all music would just sound the same forever. Rap has overtaken rock as the anti-establishment genre. If youre looking for stuff that sounds similar to old school rock though then you should look into lo-fi alternative and folk.
