Lop Lop is a studio album by the Japanese noise musician Merzbow. It was released on December 3, 2011 by the Italian label Rustblade, and is his first release on the label. The title is a reference to Loplop, a bird-like alter ego of dada and surrealist Max Ernst. Rustblade says that Lop Lop is "a step in a new direction" and that "synths and guitars scream and sing in a way which allows them to be heard through all the oppressive noise".
