Chilean singer, songwriter and producer, known for producing Kudai, Supernova and Stereo 3 in collaboration with Cristián Heyne. At the end of 2009 he released his first solo album, Valiente. He was also the leader of the band Glup!

His duo with Cristián Heyne, in Packman, allowed the conceptualization and development of the vocal trios Supernova and Stereo 3 (both shared in the tasks of composition and production), with the first one they achieved a nomination to the Latin Grammy Awards 2002 for best pop album by duo or group; as well as the group Gufi. The commercial success of both projects assured him future commissions that have not stopped until today, in which Stambuk acts as a general conceptualizer of sound and, sometimes, image.

Starting in 2006, and in parallel to his theater studies, Stambuk worked on Frijoles, the first Chilean experiment in what was defined as a "fiction group", and which anonymously integrated the work of Stambuk, Luis Tata Bigorra (ex Los Tetas) and Chico Claudio. Frijoles presented that year the album Elefantes volviendo a casa, in which Frijoles was once again in charge of preparing the electronic bases and playing several instruments. In 2013, he is producer and composer of the CD of the Mexican singer Maite Perroni titled "Eclipse de Luna", which has some of his participation in it as with the song "Ojos Divinos". He also had a sentimental relationship with the singer since he started producing her album, which lasted seven years. During the same period, he directed two film projects starring Perroni.
