Rubén Blades Bellido de Luna (born July 16, 1948), professionally known as Rubén Blades, is a Panamanian salsa singer, songwriter, actor, Latin jazz musician, and activist, performing musically most often in the Afro-Cuban and Latin jazz genres. As songwriter, Blades brought the lyrical sophistication of Central American nueva canción and Cuban nueva trova as well as experimental tempos and politically inspired Nuyorican salsa to his music, creating thinking persons' (salsa) dance music. Blades has composed dozens of musical hits, the most famous of which is "Pedro Navaja," a song about a neighborhood thug who appears to die during a robbery (his song "Sorpresas" continues the story), inspired by "Mack the Knife." He also composed and sings what many Panamanians consider their second national anthem. The song is titled "Patria" (Fatherland).
