Glad you brought this up. The death of MTV, the album experience (because of going digital), and streaming have all contributed to the idea that rock is dead. And the new metrics to determine success (streaming numbers, download numbers, YouTube numbers) are harder to analyze and accept as real success.
Yet, all of the newer rock bands I’ve gotten into were all found on YouTube, not radio or TV. Dorothy, The Pretty Reckless, Black Stone Cherry, Walk off the Earth, Gary Clarke Jr are all artists I discovered streaming.
Rock Radio stations are sad though. They COULD play the new stuff but they don’t. They don’t even play new stuff from legacy bands. It’s insane to me. It’s like they are trying not to attract new listeners.
