Joyce changed a huge amount and FW is at the end of that. Go back to Dubliners or Portrait and he isn't impenetrable at all. Ulysses is somewhere in between.
In jazz, this is the album "The world of Cecil Taylor". Previously he's doing Coltrane-class stuff; there's even an album that's alternatively credited to Coltrane or him depending on pressing. Afterwards who knows what the hell is going on. But "Lazy Afternoon" with Archie Shepp on the sax, man... that's my speed.
Or Joyce is just that impenetrable. Have you seen Finnegans Wake?
