Ellen Lucille "Evelyn" Thomas (August 22, 1953 – July 21, 2024) was an American singer from Chicago, Illinois, best known for the hi-NRG dance hits "High Energy", "Masquerade", "Standing at the Crossroads", "Reflections", and "Weak Spot".

[1] Although best known worldwide for her 1980s hi-NRG club hits,[2] Thomas recorded and performed disco, Eurobeat, R&B, and dance music songs in the 1980s.

She was discovered by British producer Ian Levine, who was in the United States in 1975 scouting for gospel and soul singers he could promote in the UK.

[citation needed] By 1984, Levine had re-established himself as a producer and asked Thomas to come to London to record a new track "High Energy".

A second Thomas release that summer fared even better on the dance charts, with "How Many Hearts" narrowly missing the top 10, peaking at number 11.
