He then became an actor in the Célia Helena Theatre, performing in the musical comedy Cazas de Cazuza in 2000.

After that Jay Vaquer achieved his first popular success in the same year with his first album "Nem Tão São" with the medium-size hit "A Miragem" ("The Mirage") and the second single "Aponta de um Iceberg".

But the radio stations seemed not to notice the success of the singles (probably a fault of his record label).

Four years later, in 2004, Vaquer released his second album "Vendo A Mim Mesmo", and he gained the attention of radio stations with the hit "Pode Agradecer" ("You May Thank Me"), which granted him brief fame.

On 5 July, he premiered the first single of this production "Longe Aqui", in his official Myspace.
