In 1989, two college bands from the University of the Philippines, Diliman were both in search of new members for a new group. Curfew, which consisted of Buddy Zabala on bass, Raimund Marasigan on drums and Marcus Adoro on guitars met up with Sunday School, which consisted of Ely Buendia on vocals and Raimund as session drummer in December of the same year. Ely's first two college bands (Bluidie Tryste and Sunday School) were too unstable, so he decided to post an audition notice on a university message board. Only Raimund, Buddy, and Marcus showed up (Raimund was first since he knew Ely and performed with him before, then Buddy and Marcus were next). According to an interview with Myx, Raimund said he first auditioned as bassist while Buddy as drummer. But they noticed that it did not sound right, the two switched places, and the rest was history.
The four decided to form a new group, calling themselves Eraserheads. The band took their name from the movie "Eraserhead" by surrealist director David Lynch, which they picked up while reading a magazine. They did mostly covers, playing every gig in school they've managed to get into. Eventually, they made the rounds of Manila's rock club circuit, achieving little success.
The band found that they weren't good at playing covers, so they concentrated on writing their own material instead. "After all, if we committed a mistake, no one would recognize it since they don't know the song, right?" Buendia explained.Their new, original songs, played live, soon earned them a cult following in the university, which gradually spread outside the campus. One of the songs, a pop song entitled, "Pare Ko," became very popular, partly because of lyrics that included a few obscenities.
The band recorded a nine-song demo tape in the garage of Marasigan's provincial home (in Candelaria, Quezon) on January 6, 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!, an irreverent response to those who turned them down.
Meanwhile, Buendia became employed as a student copywriter by BMG Records Pilipinas (now part of Sony BMG Music Entertainment). He worked with BMG during the day and wrote songs with the band during the night. Eventually, the songs of Buendia and the band caught the attention of BMG A&R Director Vic Valenciano. Valenciano listened to the songs and then commented that they were very raw technically, but that there was something promising in them. Subsequently, BMG gave Eraserheads' songs a try.In 1992, BMG signed up the band for a three-year record deal.
