The band recorded a nine-song demo tape in the garage of Marasigan's provincial home (in Candelaria, Quezon) on January 26, 1991. They then shopped the demo cassette around record labels, clubs, and radio stations, hoping to have their songs reach the public. However, they were rejected at every turn, with one recording label deeming that their demo was "not pop enough". In May 1991, a professor-friend teaching Humanities, Robin Rivera, helped them re-record and mix better versions of the demo songs on a four-track DAT recorder. The new demo was named "Pop-U!", titled as an irreverent response to those who turned them down.
