Alyson Williams is an American R&B singer who gained prominence in the late 1980s and early 1990s. Known for her rich, soulful vocal style, she was the first female artist signed to Def Jam Records. Her most notable works include the hits "Just Call My Name" and "Sleep Talk," both of which were instrumental in carving a space for R&B within the largely hip-hop oriented label. While her contributions to the genre were significant, her influence is often understated in the wider narrative of music history.
