I can't believe I forgot Cowboy Bebop ("Toys in the Attic" is my favorite episode with "Mushroom Samba" a close second). Samurai Shamploo, IME, is better as background noise during a trip, rather than something immediately absorbing. I've never enjoyed "Space Dandy.I advice Shin'ichiro Watanabe's work (Cowboy Bebop, Samurai Shamploo or Space Dandy for instance), this is a psychedelic and a bit hysteric approach of what is often a violent reality, quality will be there trust
