Gustavo Cerati (Born Gustavo Adrián Cerati Clark on August 11, 1959), is a singer-songwriter, composer, and rock producer. He is primarily known as the lead singer, songwriter, and guitarist of Soda Stereo (1982–1997), considered by many to be one of the most important and influential bands of Latin Rock. His work inside and outside of Soda Stereo makes him one of the most recognizable figures in Ibero-American rock. His solo career began in the early 1990s when on hiatus from Soda Stereo Cerati recorded his first solo album Amor Amarillo (Yellow Love).

Cerati has experimented with various musical genres, including electronic music (Plan V) and symphonic music. Throughout his career Cerati has been nominated for various Grammy, MTV, and Gardel awards. In 2007, Cerati reunited with Soda Stereo for a reunion tour Me Veras Volver Tour. On the 15th of May 2010 Cerati suffered a cerebral stroke after a show in Venezuela. Since then he remains in a coma under respiratory aide.

Cerati was born on the 11th of August 1959 in Buenos Aires, Argentina. He was the oldest son of the engineer and accountant Juan José Cerati, and Lilian Clark. From an early age Cerati showed an interest in music. His first incursion into music was a broomstick band that he formed in elementary school. Besides music, Cerati enjoyed drawing. He would spend long hours drawing superheroes such as “Superbrain" (similar to Superman, minus the predilection to kryptonite). He was an able athlete who practiced swimming and athletics. He won second place in a competition for the Billiken magazine after running 100 meters in an intercollegiate competition. One of Cerati’s main activities during his youth was directing the choir for the College, where he was suspended for burping during mass (he was later pardoned after winning a singing competition). As a teenager he worked as a medical assistant at the Boehringer laboratory in Argentina in 1981. A few years later he served in the Argentinian military.
