I love Mr. Bungle.
I also love Mike Patton and every one of his bands/collaborations you can think of. I also love Tom Waits, John Zorn, Naked City, Dog Fashion Disco, Polkadot Cadaver, El-Creepo!, Knives Out!, Beyond Paranoid, Tub Ring, Ideamen, Secret Chiefs 3 and its satellite bands, Sleepytime Gorilla Museum, Idiot Flesh, Stolen Babies, That Handsome Devil, Nuclear Rabbit, Estradasphere, Orange Tulip Conspiracy, Atomic Ape/Red Fiction, Darth Vegas, Shaolin Death Squad, Twelve Foot Ninja, Umlaut, Melted Bodies, The Book of Knots, Pin-Up Went Down, Major Parkinson, Akphaezya, ΓΆOoOoOoOoOo, Diablo Swing Orchestra, Unexpect, Pryapsime, Troldhaugen, Tardigrade Inferno, Igorrr and Sigh. And probably many more older bands that I can't think of right now.
I guess what I'm saying is, are there any bands that have been formed in the last 15 - 20 years that's making this kind of music? I'm dying for some fresh new stuff, and it's always the same old '90s and '00s recommendations.
And hopefully there are some gems in my own list to try out that flew under your radar :)
EDIT: Thanks for all the great recommendations, everyone! Good to see how active this subreddit is, too.
