WHAT IS THE MOST UNIQUE SONG THAT YOU HAVE EVER HEARD?

Jay Leonhart  Salamander pie

Maggot Brain by Funkadelic

Spirit in The Sky  - Norman Greenbaum

Depends on how you define “unique”…..

If you consider any bottom-feeder releases, you may get “disgustingly evil” offerings and you now get the infamous Arthur Brown with “Fire”. I hated it from the time it first was released.
It is with some trepidation that I even highlight it now.

If you consider “weird” to a point where one wonders if - in a perfect world - the artist and performance could be somehow removed from the gene pool , you can get Tiny Tim and “tiptoe Through the Tulips”

Yup …. They do walk among us …..

At the other end of the audio spectrum, if you consider “unique” in the context of “virtuosos” you get Les Paul and Chet Atkins as “Chester and Lester”
