His entry occurred to replace Marcos Mundstock, who had taken a momentary leave. "At that time I participated as a guest in a single number, the 'Pieza en forma de tango' Piece," remembers Acher.

He learned to play the clarinet and formed a traditional jazz group.

Shortly after entering Les Luthiers, he composed the Manuela's blues. Several other jazz works and pieces from other genres would follow. Interpretively, he was noted for his ability with wind instruments, although he also demonstrated his skills as a pianist in some works, such as the live versions of Piece in the form of tango, La Chanson de Les Luthiers and Oi Gadóñaya and others.

Later, with Navarro, he would successfully present the show of the same name at the Colón Theater, the Coliseum Theater, the Opera Theater and the Argentinian Theater in La Plata.
