Exposito e Sua Orquestra - Bossa With a Beat

I thought it was very difficult to show a never released Brazilian Maestro at Loronix, behind the names we already know, such as Portinho, Zaccarias, Luiz Arruda Paes, Carioca, and many, many others. I was wrong again. Caetano is now showing us a never released Maestro, Exposito, better, Maestro Expósito. I'm curious to hear feedback from Loronixers, should be tremendous.

This is Expósito e Sua Orquestra - Bossa with a Beat (no date), for RCA Victor. It is amazing that zecalouro has never shown before any other Maestro Expósito record, there are many, mainly in the 60's. My searches were not successful when trying to gather more info about Maestro Expósito, the back cover is also disappointing, bringing only a linear notes written in Portuguese and English to target the overseas audience. I hope someone can bring more clarification. Tracks include:
