is the debut studio album by the Philippine alternative rock band Eraserheads, first released on July 1, 1993 by BMG Records (Pilipinas) Inc.

The album spawned hit singles such as "Ligaya”, “Toyang”, and “Pare Ko”, best known for its explicit lyrics.

[2] On January 26, 1991, the band recorded a nine-song demo tape at the house garage of drummer Raymund Marasigan, in Candelaria, Quezon.

Marasigan gave a copy to his Humanities professor Robin Rivera, who assisted them in remixing the demo recordings to a higher quality.

Midway through a session, Formoso abruptly left the studio for undisclosed reasons, forcing the band to finish producing the rest of the album.

[7][8] The album title is a pun on the ultraelectromagnetic tops, a fictional weapon from the Japanese anime television series Voltes V, which was popular in the Philippines at the time.

Working titles included Lutong Bahay, Pekaloid, The Klasik Kapums Konsert Kookout, and Eraserheads Greatest Hits Vol.

[13] The album drew comparisons to the Beatles,[10][12] the Cure,[10] the Clash,[13] Red Hot Chili Peppers,[10] and APO Hiking Society.

Marasigan described the song as “an anti-pop statement against the people who said we couldn’t do a pop song.”[9] "Easy Ka Lang" is influenced by the local Manila Sound genre.

"Maling Akala" has reggae elements, while the final track "Combo on the Run" is an attempt at funk according to Marasigan.

paved the way for other Filipino rock bands such as Rivermaya, Siakol, Yano, Teeth, Rizal Underground, and Color It Red to similar mainstream prominence in the Philippines.
