Karis

Emerging during the mid- to late-1990s, the Puerto Rican merengue quartet Karis combined boy band looks with crossover appeal to become a tropical airplay favorite. Several major tropical airplay hits marked their brief career, including "Esa Nena No Me Quiere," "Tu Foto," "Manecumbe," "Bandolera," "No Vale la Pena," and "Tus Ojos Son," yet three of the four founding members had departed by the release of their fourth album in 2000. Following a reggaeton-driven resurgence of tropical music, the group reunited for Los 4 Fantasticos (2007), a moderately successful Pina Records project that generated a pair of hits while demonstrating their adjustment to updated musical approaches.

The four vocalists Angel Perez, Richard Nivar, Juan Luís Guzmán, and Héctor "Tito" Bonilla formed Karis in 1993. Their 1996 debut ...Y Sigue yielded the major hit "Esa Nena No Me Quiere," which reached number three on the Latin Tropical/Salsa Airplay chart and number eight on the Latin Pop Airplay chart; the follow-up "Tu Foto" also charted inside the Top Ten of the Latin Tropical/Salsa Airplay listing. Three further charting singles—"Manecumbe," "Bandolera," and "No Vale la Pena"—appeared on the 1997 sophomore album El Poder del Swing. Yo Voy por Ti (1998) introduced replacement member Raúl Armando after Angel Perez’s exit and produced the hit "Tus Ojos Son," yet it also marked the departure of Juan Luís Guzmán and Héctor "Tito" Bonilla, the former later joining merengue rivals Grupo Manía. Power of the Swing: The Come Back (2000) featured additional replacement personnel but failed commercially and generated no notable hits, after which Karis effectively disbanded.

Seven years afterward, the Yo Voy por Ti lineup of Raúl Armando, Richard Nivar, Juan Luís Guzmán, and Héctor "Tito" Bonilla reassembled for Los 4 Fantasticos on Pina Records. The nine-track set adopted a contemporary style aimed at current tastes, frequently incorporating reggaeton elements while retaining merengue foundations. The singles "Chocolate" and "La Amas Como Yo?," the latter featuring Ken-Y of reggaeton hitmakers RKM & Ken-Y, achieved respectable tropical airplay success and supported the view of the album as a moderately successful return for the mid-1990s merengue act.
