Music

How experimental do you want? Einstuerzende Neubauten made some interesting records in the eighties (and later as well). I enjoy Five on the open-ended Richter Scale.

All Bitches Die by Lingua Ignota is absolutely terrifying, in a good way (if you enjoy unhinged screaming and beautiful melody, and who doesn't?). It's not a crappy hip hop album, but deals with artist's experience of abuse and with revenge, hence the title.

Edit: Wait, you want brilliant experimental music? Check out Mr Bungle. The s/t is... funk hardcore metal, but good, I guess. The other albums, idk sinister lounge music perhaps?

I'm a massive Jim O'Rourke fan, and you can't really go wrong with any of his records. Super interesting and enigmatic guy. He really does his own thing. Would love to see him perform one day, but unfortunately he rarely leaves Japan these days. To Magnetize Money and Catch a Roving Eye is a mammoth of a record, definitely worth a listen.

Also, NTS sessions by Autechre. Just sublime.

maudlin of the Well and Kayo Dot! My two favorite bands. Both avant-garde metal bands led by Toby Driver. motW's Bath / Leaving Your Body Map are sister albums and an amazing listen back to back, start to finish. Kayo Dot's Choirs of the Eye is one of the best albums of all time, another amazing full listen.

I'll be honest, I don't really know what counts as "experimental," but I've been really liking music in this genre that I guess is called "Baroque Metal" or something like that. Igorrr and Keygen Church have been a couple favorites.

More on the jazzy side, I listened to Sungazer's album Perihelion on repeat for like two straight weeks, it's really good
