Interesting.
I'd say my wife and I (who are on the backside of our 40s) are still pretty heavily invested in our enjoyment of music. We still buy new releases religiously. We also go to the shows that we feel work out for us with the increased responsibilities we have. And of course, aren't uncomfortable. For example, we had tickets to see Anthrax/BLS/Hatebreed, and decided about an hour before going that we weren't going to stand out there in 100 degree heat with a mass of people. We've seen Anthrax and BLS multiple times -- it wasn't worth the effort. And despite that incident of having tickets and just eating them, we've become more careful on deciding to buy tickets. It has to be affordable (we skipped Alice in Chains because the ticket price for them, Bush and Breaking Benajmin were astronomical in the 100 level of the amphitheater that we had a local show at).
But we get excited for new releases from our favorite bands - Alter Bridge, Megadeth, all new records coming out we can't wait to have. Same with Muse, King's X, Nothing More and a host of others dropping new records.
We also have a daughter that is into the music we are, so that helps I guess in terms of not "giving up." But I doubt my wife and I would ever give up on finding new music and supporting the music we love. For me personally, I've noticed I gravitate more toward the legacy acts I love more than seeking out new artists. But it's not for a lack of trying. I just haven't found much out there that I really dig. The latest that I thought highly of was The Warning, the trio of gals who have started to gain some traction, and the other all-female group, Plush. Dig both those new bands. But I guess at my age, I'm searching for music that has familiar tones of what I love done in a new light.
All this shit on on Sirius/XM Octane - they all sound the same. And then...once in awhile, boom, one pops loose from the pack and I check it out.
But I won't give up on music. But I certainly have noticed I'm a bit more particular in how I spend my time on it...
p.s. I know AVATAR isn't a new group, but I'd say like three or four years ago I heard of them on satellite radio. Heard this song, clean vocals, loved it. Then I realized like 3/4 of their catalog is the whole guttural thing. That is a personal thing, but it's such a huge turn-off, and so many metal bands do it and it just doesn't work for me. Arch Enemy is another one. Music is killer. But it kills me Alissa sings the way she does when her clean voice is powerful and awesome. I say all that to say -- I tend to dig a lot of newer music...but the vocals for many bands are just a turn-off.
