Im 25 so slowly leaving the young person sphere, but I do have CDs and I did buy some at concerts.
Im a metalhead, so it was mostly for metal bands, and maybe this is specific for this genre, but every show i went to, I saw CDs being sold. I think out of 20-25 concerts, i bought 5-6 CDs, that i mostly listen to in my car. Two of them were signed by the band, so this was one more reason to buy it.
When I don't listen to metal, im into folk, rap or electro. I do have some folk CDs, that i listen to with my parents. But for rap and electro, everything happens online. My brother released a first rap EP, and printing on a CD was a very distant option for him and his crew, like 'this would be cool but that' s too much for now'. On the opposite, my friend who have a metal band immediatly started a crowdfunding to get their first EP printed on a small scale
Haha you're right I do Thx for sharing this :D
