La Conexión

After they released their debut album Nina Sky, they started recording another project.[5] Mixtape's recording was started in late 2004, and finished in mid-2005. On some of the songs, they were featuring artist, such as "Churn That Butta", "Play That Song", "You're Lying" etc. It was released as mixtape with special edition bonus DVD. Album's recording sessions just finished before the first single was released. Some songs from the album were unreleased songs from their debut studio album. The duo named the album La Conexión because they feel connection with Spanish language, Puerto Rican food and Latin music. They were also featured on Sean Paul's song "Connection" which was included on his third studio album The Trinity. There are a lot of Spanish songs on the album such as "Sueños", "La Conexión", "Toma", "Vamos Amarnos" and "Tu y Yo".

La Conexión was mixed and mastered by George Mena for Lovehouse Music Studios in Union City, New Jersey.

Mixtape was released on October 21, 2005, in United States, October 25, 2005, worldwide and December 19, 2006, as reissue in United States only. It wasn't released through Universal like their first album but through La Conexión Music Company and Traffic Records.[6] It was promoted by two singles:

• "Play That Song" was released as the lead single on September 25, 2005, through EMI Latin (now Capitol Latin). It was performed by Tony Touch featuring Nina Sky and B-Real. It peaked at number thirteen on US Bubbling Under Hot 100 chart, number seven on US Latin Tropical Airplay chart and number five on Latin Rhythm Airplay chart. This made Nina Sky two of only a few female artists who have been able to reach the Top 10 of the Latin Rhythm Airplay chart along with Ivy Queen, who currently has seven top-ten, two of them number-one singles, Latin pop singers Shakira and RBD, and American R&B singers Beyoncé, Cassie, and Keyshia Cole.[7]
• "Ladies Night" was released as the second and final single on April 17, 2006, along with tracks "Loving You" and "Your Time" It featured guest appearance by Ivy Queen. It failed to chart.

Artwork was made in 2005. The first (standard edition) cover features twins in front of the yellow-green background with white letters of the name (NINA SKY) and album (LA CONEXIÓN). Second was special edition artwork. It's a close-up of their faces and on most of the releases, it features round label, marking CD/DVD album. Both versions feature green letters OUR HERITAGE · OUR PEOPLE · OUR MUSIC on the bottom. Album was titled La Conexión because twins feel connection to Latin music, culture, Spanish language and Puerto-Rican lifestyle, since they were born in Puerto Rico. In English, the title means Connection, which is the name of the song recorded by Sean Paul featuring Nina Sky for his 2005 album The Trinity.
