stories over time of a cast of characters loosely linked through the music industry
In a post-modern style like not too dissimilar to vonnegut
each chapter can be seen almost as a stand alone vignette
edit: after re-reading your ask, I’ll admit not the weirdest book, but it’s also definitely not run of the mill narrative fiction.
If you want weird, read Naked Lunch by William Burroughs. One of the most banned books of all time for a reason, grotesque, obscene, challenging, but imo definitely worth the read and I’ll be rereading it sometime. Helps to read along with a study guide to make sure you’re following what’s going on.
