In Brazil, Almeida Prado studied with Dinorá de Carvalho (piano), Osvaldo Lacerda (harmony) and Camargo Guarnieri (composition).

Upon winning first prize for his cantata Pequenos Funerais Cantantes, based on a text by Hilda Hilst, at the I Festival de Música da Guanabara in 1969, he continued his studies in Europe.

Returning to Brazil in 1974, Almeida Prado first taught at the Conservatório Municipal de Cubatão, and then, hired by Zeferino Vaz, he became a professor at the UNICAMP Institute of the Arts, retiring in 2000.

After his retirement he settled in São Paulo, where he occasionally taught music courses and presented a radio program at Cultura FM.

In January 2007, his cantata Hiléia, Um Mural da Amazônia, based on the poem of the same name by Ives Gandra Martins, was performed at Carnegie Hall by the Orquestra Bachiana Filarmônica de São Paulo conducted by João Carlos Martins.
