Lu Pine is most notable for releasing the first recorded material from The Supremes, then known as The Primettes, in March 1960. The quartet (later a trio) recorded two sides for the label: "Tears of Sorrow" (with Diane Ross on lead) and "Pretty Baby" with Mary Wilson on lead. The single failed to make a lasting impression, and The Primettes signed with Motown Records in January 1961 as The Supremes.
