[2] At the age of 15, Guigui was the youngest clarinetist to ever play first chair in the Buenos Aires Symphony Orchestra, at the iconic Colon Theater, where he played under the tutelage of such great conductors as Herbert Von Karajan, Otto Klemperer and Arturo Toscanini.
It was there that he began developing his conducting skills and becoming highly regarded for his unique ability to interpret contemporary music true to its intent.
Guigui's perfect pitch and mesmerizing solfege quickly established him as the premier conductor for contemporary music.
Guigui went on to work alongside the likes of Itzhak Perlman, Isaac Stern, Yehudi Menuhin, Daniel Barenboim, Luciano Pavarotti, Placido Domingo, and Alexander Schneider.
Just prior to his passing, Maestro Guigui conducted three nights of the Rachmaninoff Competition at Walt Disney Concert Hall in Los Angeles, to sold out standing ovations.
