The entire albums of guitar solos are among the ones I avoided back in the day but I feel like I would probably really enjoy them these days. Frank shredding with no moronic lyrics to get in the way? sounds like an ideal situation to me.
I was never big on Absolutely Free either. Probably felt more significant at the time, I can imagine it hitting very different back in the 60s. But now it feels like it’s stuck halfway between Freak Out and Money but without the best bits of either.
I agree with the four you named but I’d also add Hot Rats, One Size Fits All, and Roxy & Elsewhere as top tier Zappa albums.

Always thought Zappa’s album count is kinda inflated. Not to discount any of the many many side projects and various things, some of his most interesting stuff does appear on those, but if you really strip his catalog down to just the main albums he only has like 30-something proper albums. Which isn’t too crazy all things considered.

Pitchfork is as good as dead now so no shame in ignoring them anymore.

Demon Days and Plastic Beach are both among Albarns best work. Though I’ve heard them countless times by this point, almost certainly more than any given Blur album. They are staple records among millenials and Gen Z music fans. Song 2 likewise remains a staple, though no other Blur songs are.
