Griffiths scored her first major hit in 1967 with “Feel like Jumping,” an up-tempo rocksteady classic that charted in Jamaica and the UK. She would also enjoy chart success with the tunes “Truly” and “Melody Life” before cutting her first album “Marcia Griffiths at Studio One”. In 1969, she teamed with Bob Andy as a duet partner and gave us “Really Together”.  When she moved from Studio One to the Trojan label (run by musician and producer Harry Johnson),  Andy followed her and their rendition of Nina Simone’s “Young, Gifted and Black” became a major international hit in 1970. The dynamic duo charted again in 1971 with “The Pied Piper,” but in 1974 they parted ways and Griffiths  released her second solo album “Sweet Bitter Love”. It was the same year Peter and Bunny left the Wailers. Nonetheless, Marcia continued her recordings with Sonia Pottinger on the “High Note” label. In 1975, Bob Marley was searching for vocalists to fill the gap in the Wailers band. Marcia, Judy Mowatt and Rita Marley were the perfect combination. The three songbirds were still doing solo projects and were recruited heavily by Bob. The trio grew up as close friends and ended up being members of the I-Threes. Bob was so impressed that he featured them on the “Natty Dread” album. After much success, they were an integral part of the Wailers until Marley’s death in 1981.  Marcia still continued to record as a solo artist, doing a pair of albums with producer Sonia Pottinger, “Naturally” in 1978 and “Steppin” in 1979. The I-Threes  kept busy and recorded a pair of albums on their own after Marley’s passing, “Beginning” in 1983  and “Songs of Bob Marley” in 1995. 

In 1982,  Griffiths  blessed the world with the Bunny Wailer classic dance single “Electric Boogie,” which quickly became a major hit in Jamaica. The song gained widespread popularity in 1989 as the seven-year-old track jumped onto the American charts, boosted by the growing popularity of the inspired dance craze the “Electric Slide”. The dance became a regular feature at weddings, family reunions and parties which established Griffiths popularity in the United States. Both the song and dance have been featured on the Oprah Winfrey and Phil Donahue shows; the video has been aired many times on Black Entertainment TV (BET) and other nationwide music networks .Griffiths continued to record and tour internationally on a regular basis, releasing albums and singles that captures the hearts of fans across the genre. Some of her favorites are with the likes of Beres Hammond, Mikey Spice, Daville, Shaggy,  Buju Banton, and Cutty Ranks and others. She also reunited with the late Bob Andy for a pair of albums,  ”Really Together”  in 1990 and “Sweet Memories” in 1997.
