Pop-U!

'''Pop-U! '''is the demo album recorded by the Eraserheads prior to being signed as artists under BMG Music (Pilipinas), Inc. Originally recorded in cassette format, copies of the songs have resurfaced years after the band have disbanded in 2002. It features the early versions of the band's songs, including Pare Ko, Tindahan Ni Aling Nena, Milk and Money, Wishing Wells, Scorpio Rising and Toyang.

Out of the 13 tracks included in Pop-U!, 6 tracks were re-recorded and included in the band's future albums. The cover art, depicting a swarm of guitars, was hand drawn by vocalist Ely Buendia.

Background
The album was recorded with the help of Humanities professor Robin Rivera, a friend of drummer Raimund Marasigan's, who was impressed by an earlier recording of the band. Rivera agreed to lend recorders and instruments and set up the Faculty Studio at the school campus for the recording session on Holy Week of 1991.

Most of the response by recording companies to the demo was not good, with label reps commenting that the record was "not pop enough and unsuited for the airwaves".
