In 1918 Eduardo Arolas' orchestra was formed with him on first bandoneon and conductor, Manuel Pizzarro on second bandoneon, Rafael Tuegols on first violin, Horacio Gomila on second violin, Roberto Goyeneche on piano and Luis Bernstein on double bass.

This was the peak of his career, playing in both Buenos Aires and Montevideo.

Soon, Julio De Caro joined his orchestra.

1918 brought this eminently rhythmic composition: “Catamarca”, initially called “Estocada a fondo”, of which Carlos Di Sarli left us a magnificent rendition in 1940.
