Great piece. You are prob a year older than me, I'm '74, so we've been through the same stuff. Almost identical in fact, although I couldn't do the Britpop scene. Early Manchester/Liverpool, (The Smiths, The Stone Roses, Happy Mondays, The La's), yes. But Oasis and Blur grated me.
As I said, and you said, I'm slightly rekindling my love of music, but I agree, the advent of Streaming has changed the picture.
We used to buy records (from Mike's), go round someone's house, smoke a few joints, and listen to the new album. It was a ritual, an event, a discovery. Then we'd play it again, and talk about it. Argue about it. 'That was a crap album. They've really lost it!'
I'm sure people in their twenties get a huge kick out of music and albums and gigs, but perhaps the induction, the ceremony if you like, has changed somewhat. Or not?
