Sandwich is a Filipino rock band that was formed in 1998 by Raimund Marasigan and Diego Castillo for the purpose of fulfilling their mutual desire to work together. Castillo recruited former band mates from The Aga Muhlach Experience Mike Dizon (of The Teeth & Pedicab) to play drums and Myrene Academia (of Imago & Duster)to handle bass duties. Sandwich was searching for a vocalist when music video director Marie Jamora recommended her friend Marc Abaya. A few years earlier, Marasigan was a judge at a contest where Marc Abaya jammed to a Beastie Boys song with his high-school band, Shirley Beans. Abaya then joined Sandwich, but was later replaced by Mong Alcaraz of the band Chicosci.
