Kero Kero Bonito (sometimes shortened to KKB) is a British band from London, England. The band consists of vocalist Sarah Midori Perry, producer Gus Lobban, and producer Jamie Bulled. KKB came to life when Loban & Bulled posted an advertisement on MixB, an online bulletin board for Japanese expatriates, looking for a singer who could speak Japanese. Sarah was one of the first to respond and the group quickly got to work on Intro Bonito, their debut mixtape released through double denim records.
