(AllHipHop News) Grammy Award winning Puerto Rican rap duo Calle 13 recently discussed their new album Entren Los Que Quieren (Everyone is Welcome), which group members Residente and Visitante believe is their most “mature” effort to date. The controversial, Latino, Reggaton-influenced, Hip-Hop group’s 4th album features a variety of songs calling for cultural unity, including the first single “Calma Pueblo,” which features Mars Volta’s Omar Rodriguez. The video for “Calma Pueblo” has already caused controversy because of the nude actors and actresses running around the business district of San Juan. It was a call to wake up, Residente said of the video. Its like, drop everything. I know there are times when one cant drop everything, but at least to have that spirit to be able to drop everything suddenly and give a chance to other things that are important. Both group members agree that touring with the 11-piece band that is featured on Entren Los Que Quieran has allowed their sound to progress beyond the reggaeton-sound the group has been associated with. Were not afraid to put live instrumentation on the album, Residente continued. Once you work a lot with live musicians, it makes it hard to work with canned electronic stuffit feels empty.Calle 13’s Entren Los Que Quieran is due in stores on November 23rd.
