One of the most successful and respected female reggae vocalists, Marcia Griffiths first gained recognition beyond the shores of her native Jamaica with the 1970 hit single Young, Gifted and Black. Then part of the duo Bob and Marcia (with singer Bob Andy), Griffiths soon branched out on her own, forming the influential vocal group I-Threes in 1974. Along with Judy Mowatt and Rita Marley, the trio backed Bob Marley during his tours and recordings until his death in 1981. Around that time, Griffiths released another global hit, Electric Boogie, which launched the popular "electric slide" dance sequence.
