In 2011, he was a judge in the Chilean TV show Factor X. Bosio began his contact with music at age 11, when he first heard The Beatles and became determined to learn to play bass guitar.

He was part of "The Morgan," a band that also included Sandra Baylac, Hugo Dop, Christian Hansen, Pablo Rodriguez, Charly Amato, Osvaldo Kaplan, Andres Calamaro, and eventually, Gustavo Cerati.

Zeta and Gustavo shared the same musical tastes and dreams, and began a search for integrating a punk rock group inspired by The Police (who played the same year in Argentina), with their own songs in Spanish.

Cerati first joined The Morgan and then formed a band called the Stress (along with Charlie Amato and drummer Pablo Guadalupe), then Erekto Project with Andres Calamaro.

Soda Stereo was dissolved in September 1997 and subsequently Zeta worked with other groups, first through the web Under Project, then as manager of Sony Music Argentina, and in more recent years with Alert Discos.

In addition to hosting the show Keep Rockin on Radio Rock & Pop, Zeta toured as a DJ performing in various parts of Latin America in what were called Live Sessions.

He has stated that he is fascinated by electronic music, dance and Dancefloor, and in addition to being a DJ, Zeta has plans to release a solo album with his mixes and compositions.
