Corpse Flower is a collaborative album by American singer Mike Patton and French composer Jean-Claude Vannier, released on September 13, 2019, through Ipecac Recordings.

called it "an album for completists", while Uncut felt that Patton "rises to the occasion throughout" and the "swooping strings and Escher-like melodic structures of "Camion" and "Yard Bull" are reassuringly familiar to Vannier enthusiasts".

[4] Alun Hamnett of Record Collector wrote, "That Mike Patton and Jean-Claude Vannier should get together to make an album was not necessarily implausible, but neither was it expected.

[6] Thom Jurek of AllMusic stated that the "set crisscrosses many genres" and "is ultimately rooted in exploration and adventure yet grounded in sleazy chanson, lounge tropes, blues, cinema music, and sound library tropes", remarking that it is "a dark jewel from two remarkable musical iconoclasts" and "a high-water mark for both men, albeit one born from the belly of hell itself".

[7] Dafydd Jenkins of Loud and Quiet called it both "questionable tripe from creepy old men raging against the dying of the light" as well as "a pornographic text of premeditated, nothing-left-to-lose hideousness, openly goading the listener to hate it.
