Marjorie Ann Johnson was born in Shreveport, Louisiana, United States. Raised as a devout church goer, Evans early exposure to music was via gospel. In 1958, she moved to Los Angeles. She initially sang as a backing vocalist with Billy Ward between 1958 and 1964, before joining the Ron Marshall Orchestra between 1964 and 1969. She then successfully auditioned to join Johnny Otis Band. During her four-year stay there, she performed on The Johnny Otis ShowLive at Monterey and Cuttin' Up albums. In addition to her recording and performing duties, Evans used her influence to help set up the Southern California Blues Society to help promote the art form through education and sponsorship. Evans commenced her solo career in 1973, and found almost immediate chart success. Her track "Good Feeling" entered the R&B chart on June 30, 1973 for four weeks, reaching number 55. However, it was another four years before "Good Thing Queen - Part 1" entered the same chart listing on July 9, 1977 for eight weeks, peaking at number 47. In 1975 she supplied backing vocals on Donald Byrd's album, Stepping into Tomorrow. Also sandwiched between these hits, in November 1975, Evans appeared on German television filmed at the Berlin-based Jazz Tage concert with Johnny "Guitar" Watson, Bo Diddley and James Booker. Using Bobby Bland as her record producer and part-time song writing partner, Evans co-wrote the song "Soon As the Weather Breaks", which reached number 76 for Bland in 1980. In 1980, Evans performed at the San Francisco Blues Festival and Long Beach Blues Festival, repeating the feat at the latter a year later. Her touring saw Evans take part in the AmericanFolk Blues Festivals in 1981, 1982 and 1985. In 1983, Evans was granted the Keepin' the Blues Alive Award by the Blues Foundation. Performing into the early 1990s, Evans toured the States, Canada and Europe as well as appearing with Jay McShann at the Toronto Jazz Festival. In the same decade, Evans continued her welfare work, by helping to organise the 5-4 Optimist Club for children from the South Central Los Angeles district. Her 1996 album, Drowning in the Sea of Love is her most recent solo-output. She recorded three albums with the Swiss blues singer Philipp Fankhauser in 1989, 1994 and 2016 respectively. In 2015 and 2016, Evans returned to the stage, guesting with Fankhauser in front of sold out venues throughout Switzerland.
