Sandwich is a Filipino rock band that was formed in 1995 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) to play drums and Myrene Academia (of Imago) to handle bass duties. Marasigan was a judge at a contest where Marc Abaya jammed to a Beastie Boys song with his band, Shirley Beans. He was then recruited by Marasigan to be their vocalist and later replaced by Mong Alcaraz of Chicosci.
They signed with Sony Music, and released their debut album, Grip, Stand, Throw, with much success, thanks to its carrier single, "Butterfly Carnival." The band won three awards at the 1999 NU 107 Rock Awards: Album of the Year, Best New Artist, and Song of the Year.
Abaya left Sandwich in 2005, in an effort to cope with the difficulty of juggling his job as an MTV VJ, and his obligations to his other band, Kjwan.
