I don't think you're looking in the right places, rock music is booming at the moment. King Gizzard, BCNR, black midi, IDLES, Slift, Shame, Fontaines D.C. I could genuinely go on and on, theres a miriad of bands out at the moment that are pushing rock forward and bringing it to new audiences. It's not mainstream the way it once was but it's certainly not a fad.
