S.E.B is Sebastian Castro's first album. The album is both Sebastian's nickname and a clever acronym for "Sex Eye Ball"--colloquial Filipino slang for "hooking up." The album is a fusion of EDM and alternative pop, with influences ranging from underground 80's British indiepop to middle eastern dance. Of the nine tracks, seven are in English and two are in Filipino. Although Sebastian's known for traveling sporadically, he has called the Philippines "home" in multiple interviews and has even championed multiple Filipino advocacies, including anti-corruption rallies, HIV awareness, and natural disaster relief efforts.
