A life in music.
I’m an Argentine harmonica player and guitarist, bringing both instruments together in a sound shaped by blues, swing, folk and Argentine roots.
For more than 20 years, I’ve explored what the harmonica can say across styles and stages. I’ve performed at Movistar Arena as a guest of Ke Personajes, and I teach harmonica players around the world through Harmonica School.

Official endorser
A sound I stand behind.
I’m proud to be an official endorser of Lee Oskar Harmonicas.
From blues and folk to Latin grooves and Argentine roots, I look for a harmonica sound that carries feeling and personality. This partnership is part of the music I take to the stage, the studio and my lessons.
