Like the King of Pop or the Queen of Soul, Donna Summer was bestowed a title fitting of musical royalty — the Queen of Disco.Yet unlike Michael Jackson or Aretha Franklin, it was a designation she wasn’t comfortable embracing.“I grew up on rock ‘n’ roll,” Summer once said when explaining her reluctance to claim the title.Indeed, as disco boomed then crashed in a single decade in the 1970s, Summer, the beautiful voice and face of the genre with pulsating hits like “I Feel Love,” ‘’Love to Love You Baby” and “Last Dance,” would continue to make hits incorporating the rock roots she so loved. One of her biggest hits, “She Works Hard for the Money,” came in the early 1980s and relied on a smoldering guitar solo as well as Summer’s booming voice.Summer died of cancer Thursday morning in Naples, Fla., said her publicist Brian Edwards. Her family released a statement saying they “are at peace celebrating her extraordinary life and her continued legacy.”Luminaries from Aretha Franklin to Dolly Parton and Barbra Streisand mourned the loss, as did President Barack Obama, who said he and Michelle were saddened to hear of the passing of the five-time Grammy winner. “Her voice was unforgettable, and the music industry has lost a legend far too soon,” he said. “Our thoughts and prayers go out to Donna’s family and her dedicated fans.”Elton John said in a statement that Summer was more than the Queen of Disco.“Her records sound as good today as they ever did. That she has never been inducted into the Rock ‘n’ Roll Hall of Fame is a total disgrace especially when I see the second-rate talent that has been inducted,” he said. “She is a great friend to me and to the Elton John AIDS Foundation and I will miss her greatly.”Summer may not have liked the title and later became a born-again Christian, but many remembered her best for her early years, starting with the sinful “Love to Love You Baby.”Summer, real name LaDonna Adrian Gaines, was born in 1948 in Boston. She was raised on gospel music and became the soloist in her church choir by age 10.“There was no question I would be a singer, I just always knew. I had credit in my neighborhood, people would lend me money and tell me to pay it back when I got famous,” Summer said in a 1989 interview with The Associated Press.Summer is survived by her husband, Bruce Sudano, and three daughters, Brooklyn, Mimi and Amanda.AP
