Zavaleta was the author of most of the successes of Suéter, including: «Amanece en la ruta», «Él anda diciendo», «Comiendo gefilte fish», «Desvanecidos» and «Extraño ser».[4][5]

After the breakup of the band, Zavaleta, began his solo career with his first album titled No sé, quizás, suerte, released independently in 2011. It was produced by Palo Pandolfo and Mario Breuer. This disc was not recorded in any record company, so the artist had to hang it on the Internet.[6][7][8]

In addition to his solo career, he participated in over twenty-five recordings of other artists, including: Charly Garcia, Fito Paez, Fabiana Cantilo, Los Twist, Los Auténticos Decadentes, Bersuit Vergarabat, among others.[9][10]

He had a small role in the US–Argentina co-production film, entitled The Warrior and the Sorceress in 1984, as a Zeg’s Guard and was credited as “Michael Zane”.[11]

Zavaleta died in August 2026, at the age of 71.[12]
