After climbing onto the Latin charts throughout America, Zaa recorded Segundo Sentimiento in 1998, followed by 2000's Ciego de Amor. The album sold over half a million copies in Mexico and eventually over a million globally. Zaa went back to studying the classics and in 2001 issued the best-seller De un Solo Sentimiento, which was nominated for a Latin Grammy in 2002 and also hit the top spot on the charts. Just as the entertainment media and radio programmers tried to pin him down as one kind of singer, Zaa returned to a more pop tropical style for Grandes Sentimientos in 2002. The "feeling" theme continued with 2004's audio and video package Puro Sentimiento, and he delivered his first all-bachata offering in 2005 with Bachata con Puro Sentimiento.
Despite -- or perhaps because of -- his success, Zaa was in personal crisis and beset by problems including an addiction to alcohol. His label issued the stopgap retrospective La Historia de Charlie Zaa in 2006 while the singer got sober and turned his life around. When he returned to the studio in late 2009, he made De Bohemia. Issued in 2010, it is a collection of boleros associated with the late vocalist Orlando Contreras
, to whom the album was dedicated. The comeback album hit the top spot on the Latin albums chart. Zaa toured relentlessly behind the recording across Latin America and the United States, but was well aware of how overwork could affect his health. The album stayed on the charts for 62 weeks before he left the road.
Apart from occasional concert and television appearances, Zaa stayed away from the recording limelight for the better part of five years. When he did return, it was with producer Sergio George
in a tropical style. Offering his well-developed -- and by now signature -- meld of bolero and bachata, Zaa covered Joan Sebastian
's "Un Idiota" and recorded his entire album as a tribute to the recently deceased singer and songwriter. The track was released as his first single and hit number one on the tropical songs chart. The album, Mi Mejor Regalo, was issued in November of 2015 and scored the top spot on the tropical albums chart. In 2017 Zaa released Celebracion, a collection of new live versions of songs from his 1996 debut, Sentimientos. ~ Drago Bonacich & Thom Jurek, Rovi
