i dont know much about SB post Neal Morse, but this kind of reminds me of something ive always had in my head
it seems that it's much harder for a young band (or even 10-15 years old band) to find sucess, or popularity, when it seems like older bands keep grabbing the spotlight, and media does not focus on younger/less popular bands.
for example, everyone still talks about Metallica, AC/DC, Rolling Stones, Phish, Yes, Genesis, etc. all these bands have had their day in the sun and have millions upon millions of dollars. Yet all the underground metal, hard rock, rock, jam bands, prog rock, and prog/pop bands (respectively) have no shot when these 20-30+ year old bands still get lots of attention. those were just a few examples and im sure i could come up with more.
and it's not even bands or artists that are still around. Half the Beatles are dead, yet they have more sales this week than Spock's Beard's entire existence. Even jazz guys cant get anywhere with people still talking about Bird, Coltrane, Miles, Dizzy, etc... or the veterans like Herbie, Corea, Burton, etc... back in the 60s and 70s (im guessing, from whatever interviews/documentaries etc ive seen) this didnt happen because the times changed and lots of people didnt look back, in other words; the youth didnt care what their parents or grandparents liked, and wanted something new, so the media would jump on that. Nowadays it doesnt seem like that happens much, and you have to persevere to get some decent exposure (shit, look at Dream Theater)
i know not every band can make it, but i mean, the only new bands i know of that have a good level of mainstream success, arent very good IMO
sorry about the rant, i know it wasnt completely on topic, but take it as you will.
