Derek Erdman

[1] His notable works and projects include his vibrant paintings,[2] irreverent prints,[3] phone-prank album Kathy McGinty[4] and his portrayal of Rap Master Maurice.

Callers expecting to have phone sex with a young woman instead conversed with "Kathy," who repeats herself often, responds bizarrely to questions, and becomes increasingly unhinged as the calls progress.

[13] Professor Jacob Smith of Northwestern University discussed the cultural significance of the Kathy McGinty calls in his 2008 book Vocal Tracks: Performance and Sound Media.

[16] Erdman has appeared as Rap Master Maurice on Chicago's CAN TV musical television show Chic-a-Go-Go[18] and on a track of the Ohio noise band SLOTH / MAMMOTH split 7-inch.

[20] When F. Scott Fitzgerald's The Great Gatsby entered the public domain in 2021, Erdman published an illustrated edition with the text of the famous novel in all caps, with no punctuation.
