Five-time Grammy Award winner Donna Summer was renowned for being the Queen of high-energy disco.
She shot to fame in the 1970s singing a string of classic disco hits, including Love to Love You Baby, Bad Girls and Hot Stuff.
During her 40-year career, she worked with the likes of Giorgio Moroder, David Geffen, Stock Aitken and Waterman, and Barbra Streisand. Her last single, To Paris with Love, topped the US dance chart in 2010.
In 1977 Summer was interviewed about her single I Feel Love and said "this song became a hit because it has a high-energy vibe".
Following that interview, the description "high-energy" was increasingly applied to high-tempo disco music - or Hi-NRG, as it became known.
In 2004, Summer was inducted to the Dance Music Hall of Fame, alongside The Bee Gees and Barry Gibb. Her classic song, I Feel Love, was also inducted that night.
