After the huge success of "Vivencias", she changed gears in terms of music style and released "Portfolio" in the summer of 1990, with the help of Venezuelan singer Ricardo Montaner which was one of the producers and songwriters. With Portfolio, she performed nine sold-out concerts at Puerto Rico's Centro de Bellas Artes (making a new record on sales), and at the Madison Square Garden. During her performances at the Centro de Bellas Artes, Yolandita became the first Latin performer, and one of the earliest recording artists, to use a wireless headset microphone, allowing her to dance while she sang.
