Back in Madrid, as a protégé of Manuel de Falla, whose work he played on numerous occasions, Soriano's talent soon began to be recognized.
In 1955 he made his first tour of the Far East and in December 1959 visited the Scandinavian countries, which included a concert given before the King of Sweden on the occasion of the award of the Nobel Prize in Medicine to Dr. Severo Ochoa.
Victoria de los Angeles, outstanding soprano and a great admirer of Soriano's talent, was a keen collaborator for both concerts and recordings.
It is said that the dialogue between voice and piano achieved a perfect balance when these two artists performed together in works by Federico Mompou, Xavier Montsalvatge or Joaquin Turina.
Soriano died suddenly from a stroke on 14 April 1972 at home in Madrid, with his latest recording, Granados' Twelve Dances (EMI-Odeon, J 063-10913) still in production - a work that had already won the Grand Prix du Disque de l'Académie française.
