Musically, my dad isn’t very cool. He’s probably spent years of his time listening and cataloguing music (he was a child of Elvis, then the Beatles/Rolling Stones) and has an almost encyclopedic knowledge of the 60s/70s…but he sees all other music through that narrow lens. He frequently asks for new music recommendations… but only really likes stuff with heavy riffs and the “right” vocals (so little screaming or heavy effects) - cloud nothings, for example. Has a weird aversion to pretty much any female vocalist. It’s funny because…I used to think his depth of knowledge was pretty cool…but that has diminished as I’ve learned how fixed his ideas are. Even having said that…in the last few years I’ve decided that I wasn’t too interested in exploring too widely wrt my music tastes, and I’m happy with the fairly narrow field which I enjoy.
Aside from music though, my dad has a few traits that are pretty cool; among them being the least violent person I’ve ever known and also having a disregard for most tropes of “masculinity” (he’s a good crier, much better than me).
