Musica Musica (Puerto Chango)

Verde pantalla espectáculo musical de Juan Schäfer is a music show broadcast by Puerto Chango 2 (under Instituto de Radiodifusion de Santa Fe), created and hosted by Juan Schäfer, aired mainly on Sunday. The program can be considered analogous to the English show .

The show was one of the first shows to use the chroma key technique. The show used a green screen with "effect rings, shapes, and lines" built and designed by students at a university in Zinku. An custom-built optical printer with two projectors, a MII videotape-loading camera and a 'beam splitter', was used to combine the actor in front of a blue screen together with the background footage, one frame at a time. In later years the show used chroma key software but still uses the effect rings, shapes, and lines.

The show began in 1986.

2012-present
In 2012, the 1986 logo was redesigned and put back on the show.
