The website of arts criticism reviewed Bispo do Rosario: All Existing Materials on Earth, the first U.S. retrospective of the Brazilian artist

Bispo do Rosario: All Existing Materials on Earth, which closes May 20, "adds another name to the 'outsider' canon" writes Roberta Smith.

The Afro-Brazilian master never aspired to show his work, yet became a huge influence on Latin American art. Catch his work at Americas Society by May 20.

"This exhibition is a rare opportunity…to gain access to [Bispo's] varied forms of expression," writes Hyperalleric about Americas Society's show.

The art publication reviewed Americas Society's Bispo do Rosario: All Existing Materials on Earth, on view through May 20.

"Teetering between the real and the imagined, these objects [...] possess a ghostly, ephemeral aura," said the art publication in its May issue preview.

"[The] exhibition lays out a narrative that elucidates the artist's personal history," says the journal in its ArtSeen section.
