The sound and mastering of this compilation could be a lot better; however, this Frankie Ruiz compilation is the most comprehensive of the late singer. "Primero Fui Yo," recorded with the Tommy Olivencia Orchestra, continues to be included in the singer's repertoire (perhaps unnecessarily). For followers and those unfamiliar with Ruiz, it is a great introduction. Rodven/Polygram has yet to produce a decent compilation that offers interesting material and decent presentation and mastering. ~ José A. Estévez, Jr.
