El Nuevo Día informs that, among the Puerto Rican artists who will participate in Juanes’ Paz sin Fronteras [Peace without Borders] concert on September 20, 2009 in Havana are Olga Tañón and hip-hop duo Calle 13. They will joining Juanes, Miguel Bosé, Víctor Manuel, Jovanotti, Hierbabuena and Julieta Venegas, Silvio Rodríguez, Amaury Pérez, Carlos Varela, Los Van Van, and Equis Alfonso.
Calle 13 is an award-winning hip-hop and alternative reggaetón duo formed by lead singer and songwriter Residente (René Pérez Joglar) and his half-brother Visitante (Eduardo José Cabra Martínez) with the participation of their sister PG-13 (Ileana Cabra Joglar) providing female vocals. They are recognized for their creative videos and alternative lyrics, through which they provide biting social commentary with a twist of humor.

Olga Tañón is an internationally known, award-winning merengue singer characterized by her husky-voiced style and strong lyrics. She began her career singing in the all-female groups Las Nenas and Chantelle. In 1992 she signed with WEA Latina as a solo artist and released her first of many albums, Sola. Although she has earned the title of “Queen of Merengue,” she has a diverse production, singing salsa, cumbia, pop tunes, and ballads.
As a fan of Calle 13, I would like to share one of my recent favorites, “La Perla,” with the participation of Rubén Blades:
