Zsa Zsa Padilla tackles interesting and challenging material on
Iisa (Only One), and utilizes her excellent voice, which is versatile and strong, but also delicate and intimate when needed, with only a minimum of easy-listening love songs. "Litong-lito't, Gulong-gulo" (Confused), for example, is a flashy, show-like tune, replete with a rambunctious horn section and jazz-inflected saxophone fills.
Padilla sounds loose and relaxed here, and in fine form. "Narito Ka" (You're Here) is an intimate ballad with an unusual, almost strange melody, sounding somewhat Japanese influenced. The tune is pretty, and she handles the delicate nuances with aplomb. "Mula Sa Puso" (From the Heart) is another pretty and intimate ballad. The melody is strikingly beautiful, and again
Padilla shines. The album contains several flashy, show business-type numbers, including "Dead Serious," which opens with gaudy horn work, while other parts of the song feature hard-edged guitar and showy keyboard fills. The song is a bit much, but
Padilla once again handles it with confidence. Not all songs work entirely however, and the album sounds uneven as a result, but that isn't
Padilla's fault. She sounds loose and relaxed throughout, and one can say
Padilla has one of the best voices in the Philippines.
