"Father of All..." is a song by American rock band Green Day, released as the lead single from their thirteenth studio album, Father of All Motherfuckers, on September 10, 2019.
Lead vocalist Billie Joe Armstrong has stated the song is about "making people feel bad." Armstrong added "Rock and roll sometimes has become so tame because a lot of rock acts are always trying to look for the feel-good song of the year or something." Despite that, Rolling Stone described the song as "bright, upbeat and a big departure from the tone of 2016's Revolution Radio."
A departure in sound for the band, the song has been described as garage rock revival[4] and garage punk. Containing dirty guitars, grooving bass, and rolling drums, as well as filtered and falsetto vocals, it has been compared their tenth studio album ¡Dos! (2012) and their side-project Foxboro Hot Tubs.
