Don't do drugs, but rock music and illegal substances just go so well hand in hand sometimes. However, there are songs able to give you pretty much the same effect from a mere listen or two. So without any ado, check out the songs that will get you high on their own below.
Note that the list is a bit combined and includes both entire albums and individual songs, because f--k you. Just kiddin', on to the list.
Pink Floyd - "Ummagumma"
Capturing Pink Floyd at the height of their psychedelic prowess, "Ummagumma" is one hell of a trip. "Set the Controls for the Heart of the Sun," "Careful With That Axe Eugene," "Astronomy Domine," "A Saucerful of Secrets," "Several Species of Small Furry Animals Gathered Together in a Cave and Grooving with a Pict," this one's piling with trippy tunes.
Ash Ra Tempel - "Jenseits"
German cosmic rockers Ash Ra Tempel had a few weird gems in their opus, one of them being "Jenseits" off 1973's "Join Inn." It will freak you out, make you sad, and yes - make you trippy.
King Crimson - "Absent Lovers"
Possibly the greatest live album of all time, King Crimson's "Absent Lovers" caught the Adrian Bellew-fronted lineup of the Crims at its prime, resulting in a both technically proficient and highly mind-boggling effort. Seeing the guys live at the time must've been quite an experience.
Frank Zappa - "Watermelon in Easter Hay"
For the most part, Frank Zappa's "Joe's Garage" will leave you laughing on the floor, but one time late uncle Frank really lets loose, on a mesmerizing "Watermelon in Easter Hay" instrumental, the effects are quite different.
Gong - "A Sprinkling of Clouds"
The entire "You" album might as well have been here, but "A Sprinkling of Clouds" tends to stand out a bit. You should still check out the album in full, everything that follows this track is equally trippy.
Black Sabbath - "Planet Caravan"
They might be the fathers of metal, but Black Sabbath did come from the time when psychedelic rock was at an all-time high, resulting in the band delving into the "weirder" side from time to time. Check out "Planet Caravan" for their softer, "floaty" side.
Iron Butterfly - "In-A-Gadda-Da-Vida"
The song that in a way marked the beginning of heavy metal still heavily relies on psychedelia, although it doesn't quite deliver the trippy effect with as much impact as some of the other listed tunes. Still, something had to round up an even number, odd-numbered lists give me the creeps.
Tool - "Wings" (Pt. 1 + 2)
Telling a touching story of Maynard's mother, Tool's "10.000 Days" story is nothing short of a fascinating piece. Without pompous keyboard effects or cheap tricks, the tune will get you high above and beyond.
