Mable John is an American rhythm and blues vocalist best known for her work with Motown Records and Stax Records in the 1960s and '70s. She has a distinctive soulful voice and her music often features gospel-influenced, emotive vocal performances. John's most notable hit, "Your Good Thing (Is About to End)," was a top-ten R&B hit and showcases her powerful voice and emotive delivery.
