Of Valencian origin and Andalusian and Argentine roots, he comes from a family of musicians. Already from the womb he moved every time his mother played the bass in concerts. He began to study music seriously from the age of 6 under the direction of his father, who taught him music theory and piano. It was from the age of 12 when he took his first instrument, the bass, into his hands, studying it deeply and playing with various groups at a local level. Later he would become interested in the guitar, percussion and singing, studying classical guitar at the conservatory until he finished middle school as well as taking singing classes.

Later he would specialize in jazz and modern music, also taking an interest in the world of music production and recording studios, studying courses and masters until he became a music producer.

It is at the age of 17 when Héctor de Césare begins to stand out in the musical environment and is called to play with famous pop and mixed race musicians and groups of the moment, such as Girasoules or the Barbería del Sur. In addition, he has collaborated on projects with musicians of the stature of Juan Luis Giménez or Nacho Mañó, from Presuntos Implicados. He has also played and recorded in prominent projects with prestigious Spanish pop and jazz musicians, such as Ximo Tebar, Alberto Tarín, from Seguridad Social, and Perico Sambeat.
