Sui Generis' Nito Mestre moves on after 1977

From discogs:

Immediately after the disolution of Sui Generis (4), Nito Mestre, who still believed folk music had more to give, formed the band under the names of Nito Mestre y amigos (Nito Mestre and friends) who would later evolve into Nito Mestre y los desconocidos de siempre (Nito Mestre and always's Unknowns) thanks to a mention of Maria Rosa Yorio, then Charly Garcia's wife. 
The original formation included Alfredo Toth on bass gutiar and vocals, Rodolfo Gorosito on guitars, Nico Mestre on acoustic guitar and vocals, Rosa Yorio on vocals, Francisco Pratti on drums and Leo Sujatovich on keyboards. 
They debuted on 1977, at Teatro Estrellas and proved that folk rock was still alive and popular. They toured all around the country and neighboring nations. 
By this time Sujatovich was replaced by Osvaldo Caló, and they would release their first, self-named, LP with him. the immense popularity of it labeled them as the top folk band of the times and Nito as the best singer of the nation. 
The relationships between the group members wasn't as good though, and Caló would be replaced by Alejandro Lerner and later Eduardo Zvetelman. until finally stabilizing with Ciro Fogliatta on keyboards, and Juan Carlos Fontana replacing Pratti on drums. 
On 1978 they released their second LP, again self-named,. It wasn't as popular as the first because of the changes in formation and creative stagnation. 
On 1979 the released their third LP, Saltaba Sobre Las numbes (Jumped over the clouds) taking a closer approach to rock, though they were still unable to gain more public. 
On 1980, Toth and Yorio decided to leave the band, and it disbanded soon after. Nito Mestre would never enjoy the popularity he enjoyed on Sui Generis again. 


Obviously, this is the classic folk-rock Argentinian sound with the dynamic composition and delicate acoustic passages that we are so familiar with from the more famous bands like Arco Iris, Aquelarre, and Sui Generis.  I have three from the follow up band which existed as mentioned from 1977 to 1980, but the last album doesn't completely correspond in titles to the database, hopefully someone can explain the discrepancy though it might merely amount to someone being careless with assigning song titles.  Perhaps I'll later buy the last album to complete this band. All not my rips.

Note that there is a clear progression in the music from beginning to end with the first album sounding very much like the folkiest of folks from this country (like the earliest Sui Generis) and the last album approaching the great Spinetta Jade in his early 80s smooth falsettoed pop-rock grooviness.

Thus, from 1977:





And from the end:





Really great stuff.  Hugely enjoyable material here.  Will the seventies wonders never cease?
