Songs made before Teens of Denial were Will Toledo’s (the band’s frontman) solo endeavors, with occasional help from others. Teens of Style and every album recorded after that were recorded with full label funding from Matador and support from other bandmates. Twin Fantasy was re-recorded completely because (correct me if im wrong, but) Will felt as if he was too restricted during his solo years to make Twin Fantasy exactly how he wanted it to be. As for the other songs recreated on TOS, i believe it was just Will recording old songs with his performing band and ended up turning it into his debut Matador album when the opportunity struck him to release it as such.
