The band Fall Out Boy has been influenced by a lot of artists such as Green Day, the Ramones, Metallica, and Gorilla, as a group but different band members also have their own so called influences. Patrick Stump mentioned in a 2002 interview that he grew up listening to artists such as David Bowie, Prince, and Michael Jackson in which he said he was greatly influenced by them. Fall out boy has noticeably been influenced by many more groups by borrowing chord sequences from other popular songs for example, they used the chord sequence from the song “Buba O' Riley” by The who.
Throughout the show the band used a plethora of different instruments which gave every song a unique difference. The instruments consisted of both electric and acoustic guitars, several different basses, a single drum kit drums, a full sized piano, and some computer or disk jockey created beats. Every song is unique in its own way, no two songs sound the same. Some tunes were fast paced and loud while others were fast and mellow and just very different from the others. The use of different instruments sets the tone for the song. When the stage crew handed the guitarist an acoustic guitar the crowd knew that the song isn't going to be as loud, fast, or hardcore as the previous tune played
