His first album, Antonio
, was released in 1980 and included the hit "No dudaría" and a cover of Joaquín Sabina's "Pongamos que hablo de Madrid". The album was a complete commercial failure. His next two albums, Al caer el sol
(1984) and Gran Vía
(1988), also passed unnoticed. Despite of his unsuccessful attempts, he was encouraged to continue his music career by his sister's album De ley
(1992) which he had mostly composed.In 1994, thanks to the support of his fellow influencing musicians, he was invited to the Gijón concert of the Mucho más que dos
(Much more than two) tour, where he sang "Sólo le pido a Dios" (I only ask of God) in a duet with Ana Belén.He achieved commercial success with his album Cosas mías
(1995,) which would also be his last.
Shortly after the release of Cosas mías
, Flores' mother, Lola Flores, died, sending him into a deep depression. Two weeks after his mother died, he was found dead of a drug overdose. It was ruled a suicide.
After Flores' death, his music started to gain recognition. To date, numerous tributes and posthumous reissues have been made of his work.
