I can't believe we've lost another wonderful singer. Donna, like Whitney, had one of the greatest voices ever. I loved her records. She was the disco queen, and will remain so. I knew her and found her to be one of the most likable and fun people ever. She will be missed and remembered.

Tommy Davidson, who toured with Donna Summer early in his career, also tells toofab:

Donna Summer used disco to bring the most unlikely people together -- blacks, whites & everyone in between. Donna was a role model, the consummate professional. Her guidance and inspiration will forever help me reach new heights as a performer. I cherish the days I toured with her. Love to love you, baby...truly. RIP.

Nick Rhodes of Duran Duran

I just heard the very sad news that Donna Summer has passed away. For me, there is no doubt that her song ‘I Feel Love’ had a dramatic effect on modern music. It was certainly a key influence on my work with Duran Duran. Together with producer Giorgio Moroder, Donna pioneered the use of electronic sequencers in dance music. Today that sound that seems so familiar, but in 1977, it was a brave new frontier. It’s extremely rare that you hear one song that completely changes the way you perceive music. “I Feel Love” achieved that.

The Recording Academy
Five-time GRAMMY winner Donna Summer had a dynamic voice and unique musical style that helped define the dance music genre in the ‘70s. She also was an artist who crossed many musical genres, as evidenced by her GRAMMY wins in the R&B, rock, inspirational and dance categories. Her talent was a true gift to the music industry, and our thoughts and sympathies are with her family, friends and fans throughout the world during this difficult time.
