My brother ruined everything (Rant)

So if you’re on here enough you probably remember me as the kid who got Wolf on vinyl but his early 30s old big brother told his dad he was a disgusting person and that he was extremely inappropriate, well now I’m even more pissed off at him, recently I sold my Nintendo Switch and now have enough money to get a ticket to go to the Charlotte, NC concert on SeatGeek, I had the money and didn’t care about the view, I just wanted to see him perform and have fun, but when I asked my mom and dad if I could go cuz I had the money, my dad said absolutely not because MY FUCKING BROTHER told him that and now my dad won’t let me go at all, or get anymore vinyl records from him, or CDs, or pretty much anything other then listen to his music on my phone, so now I can’t go to the concert that I sold something I liked for, my brother has only ever listened to some songs from Goblin, I honestly don’t have a clue what to do, my parents are fine with me listening to ppl like 2Pac but according to them "your brother usually doesn’t care about that stuff, so we’re gonna listen to him cuz he does about this" idk anymore, can anybody help me out
