"O A e o Z (also known as A e o Z, or \"A\" e o \"Z\", Portuguese: The A and the Z) is an album by Brazilian rock band Os Mutantes. It was their first record without founding member Rita Lee, and marked a shift in their sound to progressive rock. Recorded in 1973, but shelved until 1992, this was Arnaldo Baptista's last studio record with the group."@en . "O A e o Z"@en . . . . . . "2896.0"^^ . . . .
