Twin Peaks (David Lynch)- I always knew about David Lynch because my dad always showed me clips of his movies and talked about how much of an innovative director he was, and tbf he's right. From the few episodes I have watched of this series, it's amazing. The entire environment of Twin Peaks, Washington is great and everyone seems friendly, although one of the characters is a scumbag who hits women. Overall though, Agent Cooper is an amazing detective, although his methods for figuring out clues are strange.
Grateful Dead- I have had an interest of psychedelic rock/late 60s to about early 80s rock but I never really knew about this group. I listened to like The Beatles' Psychdelic ablums (from Revolver to Magical Mystery Tour) and Frank Zappa's earlier work (which the first and second Mothers of Invention iterations were there to make fun of the flower power movement), and realizing I never really listened to The Dead, I decided to listen to a few songs by them. They're a very good band and I kind know now why their "stealie" logo is on fucking everything. It's because those products were made to steal the money right out of your wallet if you listen to them!
Ween- Oh boy. I started listening to ween recently and I'm a huge fan of them, so much to an extent I listened to every single one of their studio albums (10 if I remember right). These two dudes from New Hope were strange musical giants, but they have something for everyone. They've also worked with South Park, Spongebob, and even played themselves for a movie called It's Pat.. that realistically everyone forgets. Either way though, they have amazing music and their lore for their logo, Boognish, is some amazing writing considering that it came from two (at the time) 14 year olds.
