His Mosalini/Agri Quintet, based in Paris and co-directed by Juan José Mosalini, also featured Agri's son, Pablo, with whom the violinist often performed as a duo.

He later co-founded the Nuevo Quinteto Real with pianist Horacio Salgán, bandoneonist Leopoldo Federico (later replaced by Néstor Marconi), guitarist Ubaldo De Lío, and bassists Omar Murtagh and Oscar Giunta.

[3] Agri recorded as featured guest soloist with the Royal Philharmonic Orchestra and in Paris with flamenco guitarist Paco de Lucía, during the 1990s.

He recorded Kokoró Kará ("From the Inside," in Japanese) with José Carli, and a compilation of his works, Antonio Agri: Tango Sinfónico, in 1997.
