Making the virtuosic and vigorous style of samba-jazz her main field of expression, Leny Andrade acquired a solid reputation as a singer and improviser, acknowledged by the many top musicians who have performed with her, such as Paquito D'Rivera (who considers Andrade his favorite singer), Luiz Eça, Dick Farney, João Donato, Eumir Deodato, and Francis Hime. Leny Andrade's eclectic style became better defined with the advent of bossa nova, through which she introduced jazz elements into her singing. Finally, she opted for a synthesis of samba-jazz that refutes much of the delicacy and attention to the lyrics as proposed by bossa nova, in favor of a more energetic interpretation. The LP Registro (1979) is a good sample of her dedication to that genre. She also has albums dedicated to rootsy samba-canção/samba composers like Cartola, Leny Andrade Interpreta Cartola (1987), and Nelson Cavaquinho (Luz Negra, 1994). Throughout her career, Andrade had many hits and some of her biggest include "Estamos Aí" (Durval Ferreira/Maurício Einhorn), "A Resposta" (Marcos Valle/Paulo Sérgio Valle), and "Samba de Rei" (Marcos Vasconcellos/Pingarilho).
