Up Popped the Devil is an album by American jazz pianist Mal Waldron, recorded in 1973 and released by the Enja label.
The AllMusic review by Bob Rusch stated, "Pianist Mal Waldron's music is characterized by a heavily-brooding rhythmic quality, with the left hand usually carrying the theme at one repetitious tempo while the right hammers away in juxtaposition with a counter tempo (usually faster)".
