==Background== Siembra is the second of five collaborative duo albums produced by Rubén Blades and Willie Colón. During its time, it was the best-selling salsa record in history. It has sold over three million copies worldwide, and almost all of its songs were hits in various Latin American countries. With its rousing social commentary and unconventional sound, "Siembra" remains one of the most original and influential works in that genre. Blades' "Pedro Navaja," a song that he fashioned after Bertolt Brecht's "Threepenny Opera," is considered one of this greatest songs.
