Calle 13

From the mawkish operatic intro to the trotting, tango rhythm of lead single "Tango del Pecado," it's clear that Calle 13 are breaking new ground under the banner of reggaeton on their sophomore offering. On the aforementioned lead single -- the first of the album's many wonderful collaborations (with Tego Calderon, La Mala Rodriguez and Orishas) -- the brothers team up with Academy Award-winner Gustavo Santaolalla for a track that humorously deals with lead singer Residente's real-life relationship with Miss Universe Denise Quinones. Playful and rich, this album cements Calle 13's place as the most adventurous reggaeton act.
