Been 20 years exactly almost for an actual "concert", like just seeing one or two bands. Travelling to a venue is expensive for me as I live in the middle of nowhere. Plus I don't really have anyone to go with. I go to local gigs with my brother and his girlfriend once every month or two. They travel all over for concerts but I think I'd feel like a third wheel if I went with them, though I might tag along if it turns out they're seeing a band I really want to at some point.
I went to some festivals in 2023, it feels easier to justify the cost of travel to see a bunch of bands over a whole weekend. Was actually going to go on my own but my brother came with before he got with his gf. Might actually do one on my own next year. Rebellion in Blackpool is great and indoors which is a big plus in the UK.
