Recorded on November 28, 1969 at Columbia Studio E (three months after the Bitches Brew sessions), it was never released during Davis's lifetime. First published in 1998 as part of the Complete Bitches Brew Sessions box set, it is now one of the four bonus tracks of the Big Fun album since its expanded CD reissue in 2000.
The titular blue may evoke rarity (blue-pigmented variants of frogs are excessively rare,[1][2] though a blue species exists in South America, Dendrobates azureus) or melancholy (the blues, though the piece's mood is more whimsy and eerie than sad) or both (loneliness). Throughout the 9 minutes of this tune, a background "bwoing, bwoing" bass vamp evokes the sound of the titular frog a-leaping on his way.

Others may have seen more, but blue frogs have not been reported widely on Cape Cod."
