What do i listen to and where do i start?

wherever you want
i'd just keep in mind that his 80s music is generally considered his least accessible. it's where he started experimenting with the synclavier compositions, was focusing almost entirely on novelty songs, and towards the end of his career he got preachy about drug abuse, evangelicals and republicans. which a lot of people obviously aren't going to be interested in
it's top tier zappa, but i think it's widely considered a favorite because it's a stepping stone album
like the first zappa album that "clicked"
a lot of people that's going to be freak out
another might be hot rats
he generally stayed in a style for a couple albums so you aren't ruining it for yourself

omg it's so well structured, i'm going to be a good lad abd keep this in mind

I actually started listening to hot rats anyway since it was one of the first albums and i'm really enjoying this.

I think I might keep going chronologically while keeping an eye on this chart
Thank you guys!
