Biography
Mittoo, of partial Indo-Jamaican descent, was born in Brown's Town, Saint Ann Parish, Jamaica, and began learning to play the piano when he was three under the tutelage of his grandmother. In the 1960s, he was a member of the Skatalites, the Sheiks, the Soul Brothers, the Soul Vendors and Sound Dimension. Mittoo's compositions in this period included "Darker Shade of Black", "Feel Like Jumping", and "Baby Why". He played with Lloyd "Matador" Daley in 1968 and 1969. In the mid-1970s, he emigrated to Toronto, Ontario, Canada. There he recorded three albums, Wishbone (Summus), Reggae Magic (CTL) and Let's Put It All Together (CTL). He also set up the Stine-Jac record label, as well as running a record store. In 1970, his song "Peanie Wallie" was reworked into a song called "Duppy Conqueror" and recorded by The Wailers. Mittoo's song "Wishbone" was a hit in 1971. He performed in local Toronto lounges throughout the 1970s. Mittoo assisted Toronto-area reggae musicians, including Earth, Roots and Water, Esso Jaxxon (R. Zee Jackson), Carl Harvey, Lord Tanamo, Boyo Hammond, Carl Otway, the Sattalites, Jackie James and Jason Wilson. Mittoo continued to record for Jamaican producers in the 1970s, mostly Bunny Lee. He co-wrote "Armagideon Time" (later recorded by the Clash) with Willi Williams, released in 1980. In the 1980s, he often worked with Sugar Minott. In 1985, he travelled to Ghana with the British band Musical Youth, and while there recorded tracks that would later be released on the album Jackie Mittoo in Africa. In 1989, he briefly rejoined the Skatalites, but left when his health started to deteriorate. In 1989 and 1990, he recorded Wild Jockey for Lloyd Barnes' Wackies label. Mittoo entered a hospital on 12 December 1990 and died of cancer on 16 December at the age of 42. His funeral was held at the National Arena in Kingston, Jamaica, on 2 January 1991. Hortense Ellis, Neville 'Tinga' Stewart, Desmond "Desi Roots" Young, Ruddy Thomas, Tommy Cowan and Clement "Coxsone" Dodd were among the attendees. A memorial concert was held around the same time, with performances by Vin Gordon, Leroy "Horsemouth" Wallace, Glen 'Bagga' Fagan, Pablo Black, Robbie Lyn, Michael "Ibo" Cooper, Ken Boothe, Delroy Wilson, Carlene Davis, Tinga Stewart and others. His 1966 song, "Free Soul" with the Soul Brothers was interplayed in the 2006 Lily Allen song, "Smile". In 2013, Mittoo was referenced by Superchunk in their song "Me & You & Jackie Mittoo" from their album I Hate Music. His pioneering role and importance to reggae music in Canada, along with recordings of his performances on CBC-TV, was featured on the 2018 documentary series From the Vaults on CBC. In 2024, Mittoo's album Macka Fat was named the jury winner of the Slaight Family Polaris Heritage Prize at the 2024 Polaris Music Prize.
