Meeting of two great instrumentalists who, out of mutual admiration, decided to get together to play, compose and share the world's stages. Before meeting in person, Gabriel already knew and admired the work of Alegre, who always had arrangements for the harmonica, his instrument. Joyful, in turn, when listening to Gabriel play, he was impressed with his musical expressiveness and his ability to put so much feeling in each given note.

In the repertoire, songs such as: Erdberg, Overture, Cunhataí, Estilo Consagrado, Bachião and Gondwana, written by Alegre Corrêa; Pro Bituca, and Pro Hermeto by Gabriel Grossi.
