It’s not just that rock is disappearing (yeah I know about indie and hear a lot of great new music on Little Steven’s Underground Garage and other SXM channels).
The truth is - BANDS are disappearing!
Rick Beato explains this better than I can and has the data to prove it:
Musicians have to buck the trend to form a band and get their songs out today, and they mostly have to do it on their own, because the “music industry” could give an eff for anything other than profit.
Exactly right. There were so many bands in the 60's thru 80's that half of them you forgot about.
The advent of MTV had a lot to do with that. Bands aren’t given 2-3 records to develop anymore.
