I absolutely adore this woman. Her vocals are so soft, yet passionate at the same time. From 1973's "Just Being Myself", her's Warwick (Warrick really) with "You're Gonna Need Me."
Here's the Warwick sampled "Stop."
Also, From the same Warwick lp, here's "Don't Let My Teardrops Bother You." http://www.zshare.net/audio/62491492699ab84b/
From "The Preface", here's Slum Village's own (who ROCKED the Bells properly) Elzhi with the Warwick sampled
