This is a promo release featuring the 'most unsual novelty act in the world,' known as 'Mr. Sound Effects,' doing his many impersonations of various objects in front of a live audience. He's 'capable of producing a full scare air raid, artillery barrage or the subtle, tricky sequence of a door closing, the door knob falling off, bouncing down the porch steps and then rolling around on a cement floor.' (These quotes are from the extensive liner notes on the back of the sleeve.) A great rarity!
