I really don’t see a pattern in this thread of generational bias/favoritism. It’s certainly not something I’m interested in.Specific to the question of finally "getting" a band, best example for me would be Pearl Jam. Seeing them live brought real appreciation for their skills. Their new record, Dark Matter may be their best work yet.
I also wanted to mention the recurrent theme above of 20th century pop music being superior to recent artists; this prejudice is very poorly informed. There are so many great bands & artists making phenomenal recordings right now. I think many boomers and gen x guys have a lot of great music to learn & to "get".
