As a producer, Stump has worked with such bands as Gym Class Heroes, whose vocalist Travis McCoy is also an unabashed Daryl Hall fan and a participant in a previous Live From Daryl's House. Fall Out Boy guitarist Joe Trohman calls him "a musical genius, a mad scientist," while noted producer/performer Kenneth "Babyface" Edmonds says, "Patrick is one of the hottest dudes I've seen in a long time... He's got a great voice and a tremendous amount of talent." Fall Out Boy's fifth album, Folie a Deux, was released last December, producing the hit singles, "I Don't Care" and "America's Suitehearts."
