with regard to the rigidity in which a band must release a single, create a music video, or head out on tour. He felt groups like hip hop duo Outkast were "kicking rock's ass, because there's so much ambition." The band used more loud guitar sounds for the record. Armstrong said "We were like, 'Let's just go balls-out on the guitar sound—plug in the Les Pauls and Marshalls and let it rip'". Armstrong added tracks of acoustic guitar-playing throughout the record to augment his electric guitar rhythms and Cool's drumming. For most of the record, Dirnt used an Ampeg SVT bass amplifier, recording with his signature Fender Precision Bass. For the album, he and Cavallo strived for a "solid, big, thunderous" bass sound as opposed to one centered on countermelodies. Dirnt ran his bass guitar through an Evil Twin direct box, a staple of his recording methods since Dookie. Cool also employs unorthodox instruments for punk music—timpani, glockenspiel, and hammer bells—which he received out of a promotional deal with Ludwig. These instruments are especially evident on "Homecoming" and on "Wake Me Up When September Ends", the latter of which includes an African bead gourd that was welded to a remote hi-hat pedal for future live performances.

The second character introduced in the story is St. Jimmy, a "swaggering punk rock freedom fighter par excellence." Whatsername, "a 'Mother Revolution' figure," is introduced as a nemesis of St. Jimmy in the song "She's a Rebel". The album's story is largely indeterminate, because the group was unsure of where to lead the plot's third quarter. In this sense, Armstrong decided to leave the ending up to the listeners' imagination. The two secondary characters exemplify the record's
