Santa Rosa has taken on himself the task of keeping Tito Rodríguez's musical legacy alive and has acquired much of Tito's memorabilia, including articles of clothing, music and furniture from his home in Puerto Rico. Santa Rosa has staged several concerts and dances honoring the late singer, and recorded an album of his where with the use of modern technology, he sings "En la soledad" (In Solitude), composed by Puchi Balseiro in a duet with him. During the week of February 24, 2003 Santa Rosa organized a two-night concert at the Center of the Performing Arts in Caguas, Puerto Rico. As an introduction to the event, he arranged for his private collection of Tito Rodríguez memorabilia to be exhibited in the lobby of the center. In 2004, he released "Auténtico".
