Simplicity was a key part of the music of Minnie Riperton. Listen to her chart-topping million-seller "Lovin' You." The song's simple declaration of love is magnified by the sparse, airy backdrop of chimey electric piano and gentle acoustic guitar. "Lovin' You" went to number three R&B and number one pop in early 1975. It was listed on her Perfect Angel LP which went gold, holding the number one R&B spot for four weeks and peaking at number four pop. After the record became a hit, the singer was often asked why there's a bird chirping happily in the background. She answered that the bird's chirping was mistakenly recorded when she did the demo for the song and somehow it seemed to work, so they included it on the finished recording. Because of contract restrictions, producer Stevie Wonder's name couldn't appear on the label; instead the track was produced by Black Bull Productions (Wonder's astrological sign is Taurus, hence the bull in Black Bull). On later versions of "Lovin' You" (after the single began garnering airplay on pop stations), a low-volumed Arp string synth pad was added, probably in a unnecessary effort to fill out the sound. Wonder and her husband/frequent collaborator Richard Rudolph were at the singer's bedside when she passed away from cancer on July 12, 1979.
