Rey Ruiz performed in the well known "Cabaret Tropicana" music group. During a Cabaret Tropicana tour in the Dominican Republic, Ruiz defected, leaving the group to join some friends in the United States. Once established there, Ruiz began to gain fame as a solo salsa singer.
It took Ruiz three years after he arrived in the United States for him to release his first CD. The self-titled "Rey Ruiz" was produced by Sony Records and it earned Ruiz celebrity in such places as Puerto Rico, the Dominican Republic, Panama and Venezuela. The album also earned Ruiz a number of billboard and Premios Lo Nuestro awards, and it was a platinum album. Rey Ruiz was named the "salsa singer of the year" for 1993 by a prestigious salsa music magazine and was known for hits such as "No Me Acostumbro" and "Amiga".
Ruiz's initial success as a singer translated into small screen success as well, as he was hired by Pepsi, Miller beer and his studio company, Sony, to film commercials announcing their brand. Ruiz's second album was a various artists' compillation dedicated to salsa singers from the 1960s and 1970s. The tribute album was named "Los Soneros de Hoy". loosely translated into "Today's (salsa) performers".
Also in 1993, Ruiz released his second album. "Mi Media Mitad" ("My Other Half") was a large hit in the United States and in Europe, once again, making the Billboard hits list in the States, and topping the European charts. "Mi Media Mitad" became Ruiz's second consecutive platinum album, and it helped make Ruiz popular in Colombia as well, with a single, "Si te Preguntan" ("If They Ask You") becoming a major hit song. Soon after that album's release, Ruiz made his debut at New York's Madison Square Garden.
Ruiz's third album, "En Cuerpo y Alma" ("Body and Soul"), was released in 1995. This was Ruiz's third platinum album in a row; his songs "Estamos Solos" ("We Are Alone") and "Vuelve de Nuevo Conmigo" ("Return Once Again With Me") were international hits, and many salsa experts consider this album to be Ruiz's most important release.
In 1996, with the collaboration of famed Colombian songwriter Omar Estefano and of Ricardo Quijano, Ruiz released his fourth consecutive platinum album, named "Destino" ("Destiny"). One of the most publicly acclaimed songs in that album was "Miénteme Otra Vez" ("Lie to me Again").
His next album, 1997's "Porque es Amor' ("Because it is Love") failed to have the commercial success Ruiz's four previous releases had, ending Ruiz's streak of platinum albums at four. It did, however, contain three major hit songs, including the title song, as well as "Mi Angel" ("My Angel") and "Tú no Sabes" ("You Don't Know").
In 1998, Ruiz released a greatest hits CD, named "Exitos del Rey" ("Rey's Hits", a name which can also be interpreted as "The King's hits", since Rey means king in Spanish). By then, Ruiz owned a recording company; his next album, "Ya Ves Quien Soy" ("Now You See Who I Am"), becoming one of the first CDs to be released by Ruiz's Luna Negra ("Dark Moon") record label.
"Ya Ves Quien Soy" was another commercial success for Ruiz, particularly in Brazil. Ruiz collaborated with Brazilian singer José Augusto in this album, when the pair recorded a duet song, "Siempre Mía" ("Always Mine").
In 2000, Ruiz joined the Bohemia Records label, releasing "Fenomenal" ("Phenomenal") under that label. In 2004, he released Mi Tentacion.
In 2008 Ruiz fulfilled a life time dream by performing on stage with some of his closest musical colleagues at the Adrian Arsht Center for the Performing Arts in Miami. Along with Grammy Winner Arturo Sandoval, Objectivo Fama winner Marlon and Los Tres de La Habana, this musical collaboration was recorded for a soon to be released DVD. Ruiz, now being managed by former VP of Entertainment for SBS radio cluster Roberto Rivera,has signed on to a new recording contract which brings him back to his original label SONY/BMG with a highly anticipated album being produced by Cuco Pena one of Puerto Rico's premier musical producers and also credited for producing a Grammy Award Winning Album for Marc Anthony. Ruiz is currently enjoying a highly successful Summer Tour throughout South America and Europe as well as preparing a 2009 Tour in collaboration with another one of his close colleagues.
