One of thew trippiest ever...but very underrated....is the VERY psychedelic "Jump into the fire" by Harry Nilsson......never heard anything like the riff in any other song!
I think one of the trippiest songs is within you without you by the Beatles. Check out the video as well if you can, I'm sure LSD was a major inspiration to the video.
what about green eyed lady by sugarloaf...or spill the wine by war...and of course white rabbit! break on through by the doors...although anything by the doors is amazingly trippy!
