Query: Summer's Storybook Masterpiece

Donna Summer ruled the dancefloor in the 70's, and this album is a prime example of why. Donna's work with Giorgio Moroder & Pete Bellotte was groundbreaking & Once Upon a Time is a trip through the synthesized world of disco music, with some powerful ballads as well. Anyone familiar with the " Now I Need You/ Working the Midnight Shift" medley will agree this is one of the most beautiful arrangements in disco music. True she doesn't display her vocal talents to their fullest potential in the danceable tracks, she still delivers a very srong performance overall. I HIGHLY recommend this CD to anyone curious to experience the electronic disco sound.
