In 2003 with the experience of many years, Rostros Ocultos presented their new production on the Sony Music label, Renacer (to be reborn). With totally unreleased cuts, Renacer began a new cycle for the band and a new image. The group went on a large tour in and out of the country. The primary objective of the group was a message to all their fans and the general community about the importance of organ donation, to give live after life. So they included a song in this material titled Corazón about a little girl born with a very weak heart who is waiting for a heart transplant. Also, they added a sticker that promotes organ donation and an authorization card for those who are interested in becoming organ donors.
