Bass Anderson Barbosa, who played the Commendatore at the beginning of the opera and returned at the end as the ghost of the character embodied in his statue, made excellent use of his opportunity, especially in the final scene (Don Giovanni, a cenar teco). Endowed with a powerful voice, a distinctive tone, and excellent projection, the artist rightfully stole the scene, solely dominating it through the expressiveness of his singing, despite the naturally restrained gestures of the statue. A voice, in short, worth following.

It is important to note, however, the excellent performance of the young artist "Anderson Barbosa" as the Commendatore.

The bass Anderson Barbosa also did a great job, playing the Commendatore and his ghost. With his powerful voice and beautiful tone, he dominated the final scene in a terrifying way, with the aria Don Giovanni, a cenar teco – and only with his voice, as even his face was in shadow, and his gestures were minimal (as befits a statue).

Regarding the performance of the singers, vocally, there is much to highlight. Anderson Barbosa embodied (and, come on, disembodied...) an imposing Commendatore: a voice of excellent projection, voluminous, dark in the cemetery and banquet scenes, with good low notes and high notes that didn't sound forced.

The most consistent performance of the night was by bass Anderson Barbosa, who portrayed the oracle Calchas with excellent projection and a beautiful tone – qualities that I had already noticed in Belém when I heard him as the Commendatore in Don Giovanni.
