Although Karen Souza’s voice seems to be made for Jazz, her career began under different pseudonyms, writing songs and providing vocals to several electronic music producers, which made her part of many House hits. Karen started flirting with Jazz when she was invited to participate in the first album of the Jazz & 80’s series. Back then, no one could imagine how successful these series would become overnight. Essentials, her first album, compiles Karen’s best renditions from these albums, and it immediately became a sales success.
