Over two consecutive years, 1978 and 1979, he obtained the prestigious scholarship of the Government of Brazil to participate in the X and XI International Guitar Seminar in the city of Porto Alegre where he had the opportunity to study Guitar with Abel Carlevaro, Álvaro Pierri, Miguel Ángel Girolet and Contemporary Music with the composer Francis Schwartz [de].
On 21 June 2011, an ambitious project was first played by the Asturias Symphony Orchestra at the Príncipe Felipe Congress Hall-Auditorium in Oviedo, with Egozcue himself on the guitar, the "bandoneonista" Omar Massa, the tenor José Manuel Zapata and the "cantaora flamenca" Rocío Márquez, under the direction of Joan Albert Amargós: the orchestration of his own traditional tango arrangements as well as other compositions.
He has also been panel judge in the XVIII Contest on Spanish Dance Choreography and Flamenco celebrated at the Canal Theatre of Madrid in 2009.
And in 2010 he was finalist at the XIII Max Awards of the Scenic Arts, granted by the Spanish General Society of Authors and Editors (Sociedad General de Autores y Editores – SGAE-) and the Author Foundation (Fundación Autor), in the category of "Best music composition for scenic performance" for his original score for the performance Jazzing Flamenco.
And he has toured Argentina, Colombia, Mexico, United States, Canada, Spain, France, Italy, Germany, Switzerland, Norway, Ireland, Monaco, Romania, Greece, Turkey, Bahrain, Cyprus, Oman, Reunion Island and Jordan.
He starts his career as a performer in 1979, creating the duo Moldavsky-Egozcue with the guitarist Sergio Moldavsky, playing countless concerts around his native Argentina.
In 1992 he moves to Spain, where he creates one of his major projects, the septet Ensemble Nuevo Tango (ENT) achieving many successes.
Their last project (With closed eyes...) played by Moisés P. Sánchez (piano), Miguel Rodrigáñez (double bass), Martin Bruhn (drums), Ara Malikian (violin) and Egozcue himself on the guitar, is achieving excellent reviews wherever they present it.
In 2011 he begins a new musical project including the bandoneon -typical instrument from Argentina- in his group, and recording as a Quintet the CD "Dale" with the Argentinian bandoneonist Matías Rubino, Miguel Rodrigáñez (double bass), Martin Bruhn (drums) and Juan Pérez de Albéniz (violoncelo).
The record of this latter performance was edited in 2010 under the name "Tango y Lágrimas" and with the contribution of the "cantaores" Miguel Poveda y José Mercé.
On a different note, his successful composition Viejos Aires was choreographed in the Spanish TV series Un Paso Adelante, and by the dancer Rafael Amargo at the Innocents’ Ceremony on the Spanish TV channel Telecinco and for his dance piece "A tres bandas"; Viejos Aires has also been used by the United States Figure Skating Champion 2009 and 2010, Jeremy Abbott, for his exhibitions and contests.
