Per wiki...
"Well-known artists included the Bee Gees, ABBA, Donna Summer, Gloria Gaynor, Giorgio Moroder, Baccara, The Jacksons, Michael Jackson, Boney M., Earth Wind & Fire, Chaka Khan, Chic, KC and the Sunshine Band, Thelma Houston, Sister Sledge, Sylvester, The Trammps, Barry White, Diana Ross, Kool & the Gang, and the Village People."
You really can't say too much negative about any of these groups. Well, maybe you can about the Village People (although...who hasn't dance to YMCA?).
Earth Wind & Fire, Michael Jackson and Barry White were disco?
