Sutherland was born in Kingston, Jamaica and raised in Above Rocks in Saint Catherine Parish. She began performing in 1979, winning the Tastee Talent Contest that year (beating Paul Blake and Yellowman), with her parents managing her career while she studied at St Andrew High School. She combined her musical career with studies in business administration, and was the first artist signed by Bob Marley to his Tuff Gong label, recording "Starvation on the Land" while aged eleven. She also cut a couple of christian-flavored reggae songs produced by both Anthony "Sangie" Davis and Rita Marley, entitled, "Work And Pray" and "Hands And Hearts". After Marley's death, Sutherland performed at memorial concerts outside Jamaica, along with Ziggy Marley and the Melody Makers, the I Threes, and the Wailers.
She struggled to break through as a solo artist and after touring the US as support to Bunny Wailer, she worked as a backing vocalist at Gussie Clarke's Music Works studio. She went on to work for Donovan Germain at his Penthouse Studios, and Germain produced her 1993 hit "Action", a combination with Terror Fabulous. The track was used by the Jamaican Labour Party as their election campaign theme, and in 2007 was included by Vibe at number nineteen in its list of the fifty greatest duets of all time. In the US, "Action" reached number 43 on the Billboard Hot 100. Buju Banton's "Dickie" was remixed as "Wicked Dickie" with Sutherland adding vocals, and this topped the charts in Jamaica. She collaborated with Banton again on the single "What Am I Gonna Do".
In 2006 she performed at Reggae Sunsplash, and in 2007 she released the album Call My Name, which was a hit in Jamaica as well as on reggae charts in Florida and New York. At the Canadian Reggae Music Awards in 2008, the album was nominated in the 'Top Reggae CD/Album (International)' category, while a single from the album, "Big Tingz", was nominated as 'Best Reggae Single (International)'.
Sutherland has also appeared as a judge on the TV show Digicel Rising Stars, written for the Jamaica Observer, and been a committee member for the charity Sisters to Sisters.
