Don Johnson Big Band consists of four people: Tommy Lindgren (vocals), Kari Saarilahti (guitar), Johannes Laiho (keyboards) and Pekka Mikkonen (horns). Despite their name, they are not a big band, but instead a mix between rap, hip hop, techno, jazz, blues and rock. Regular featuring artists on DJBB gigs and albums are Juuso Hannukainen (percussion), Tero Rantanen (percussion), Emma Salokoski (vocals), and Teppo Mäkynen (turntables).
Lindgren, Saarilahti and Laiho are old high school friends. Mikkonen joined in later.
