Mexican duo Rio Roma decided to introduce their new album, "Otra vida," with a combination mini-concert and press conference in the intimate setting of the Lunario hall at the capital's Auditorio Nacional.

Between songs, brothers Raul and Jose Luis Ortega answered questions from reporters about the new release, which includes 12 original songs and a DVD of concert footage.

The performances were greeted with applause and shouts from the more than 400 mostly female fans who packed the Lunario for the event.

The songs on "Otra vida," described by the duo as entirely autobiographical, speak of solitude, regret, pain, fear of commitment and the embrace of a new relationship.

With gold and platinum discs to their credit, the Ortega brothers are still anxious to win a Grammy - they were nominated in 2011 - and explore new musical horizons, including singing in Portuguese and performing with figures such as Marc Anthony, Luis Miguel and Alejandro Sanz. EFE
