From September 15-October 31 "Calle" 13 was "Artist Speaking Tr3s" on MTV Tr3s. On November 2, 2006 the band won three Latin Grammys ("Best New Artist"; "Best Urban Album"; and "Best Short Version Video", for the song "Atrévete-te-te".) They later filmed a video along with Voltio for "Chulín Culín Chunfly", where Residente, dressed as a priest and later as Bruce Lee, is given a severe beating by a gang. On April 24, 2007, their second album "Residente o Visitante" was released. Tracks in the album were partially recorded in Puerto Rico and while on tour in Colombia, Argentina and Venezuela. While recording the album, Residente and Visitante took a trip to South America to explore areas populated by Latin America's indigenous and African-descended minorities. The duo was strongly influenced by the experience; Visitante discovered and purchased several new musical instruments on the trip including a quijada, a charango and a bombo legüero, all of which were used on the duo's song "Lllegale a Mi Guarida". Residente considered this album to be darker than the first, but also more introspective and biographical. The album garnered controversy for its sexual and religious overtones. As part of the album, Calle 13 filmed the video for their first single off the album, "Tango del Pecado", on February 25, 2007. In May 2007, the duo performed at Vive Latino, and the public answered them by throwing beer bottles filled with urine. In 2010, when taking part of the same festival, they were less bitterly welcomed. On July 2007, Calle 13 teamed up with Julio Voltio to speak out against police brutality in Puerto Rico. After recording a song titled "Tributo a la Policía", Calle 13 distributed the single free on the streets in front of the Police Headquarters of San Juan. On November 8, 2007, Calle 13, along with Orishas, performed the song "Pa'l Norte" at the 8th Annual Latin Grammy Awards, held at the Mandalay Bay Events Center in Las Vegas, Nevada. Their live performance featured the percussion/dance group Stomp. A troupe of dancers dressed in traditional Latin American garb and wearing bandannas in their faces (as if they were bandits) were also featured. Two members of the traditional Colombian folk cumbia band Los Gaiteros de San Jacinto, as well as members from an indigenous tribe local to the Gaiteros' hometown in northern Colombia, followed Residente to the stage at the beginning of the song.
