Calle 13 is a three-time Latin Grammy Award-winning and Grammy Award-nominated Puerto Rican hip hop and alternative-reggaeton duo formed by step-brothers who call themselves Residente (lead singer, writer) and Visitante (keyboards, vocals, writer, beat producer). Their sister Ileana (aka PG-13) has contributed the female vocals to some of their songs, and so has Residente's mother, Puerto Rican actress Flor Joglar de Gracia (on the single "Tango del Pecado")
