Inconsciente Colectivo, a prominent rock band from Costa Rica, was established in 1989 in the province of Cartago, specifically in Tres Ríos. The group is recognized as one of the most significant and influential entities in the history of Costa Rican rock music.

In 1990, Inconsciente Colectivo (IC) recorded its debut single, "Avenida Central." Despite facing initial rejections from several radio stations, the track ultimately gained traction and dominated the charts on "Radio Fabulosa," where it held the number one spot for five consecutive weeks.

The following year, in 1991, the band released "Frágil." Although it encountered resistance from various national radio programmers, it managed to secure airtime on "Radio Uno" with the stipulation that it would be removed from rotation if it failed to generate a minimum number of listener calls within a week. Remarkably, "Frágil" spent 16 weeks on the charts, including a month at number one, across multiple stations such as 103 "La Radio Joven," Columbia Estéreo, Fundación, Fabulosa, and Radio Sistema Universal. This success led to recognition from Radio Uno, which awarded IC the titles of "Musical Group of the Year" and "Best National Rock/Pop Song" for "Frágil."

In 1992, IC achieved first place in the "Yamaha Music Quest 92," competing against 76 national groups. Subsequently, they triumphed in the Inter-American final of the festival, earning the opportunity to represent Central and South America at the grand finale in Japan. Although they did not officially win an award, they secured third place in a popularity poll conducted by Japanese radio stations.

The band continued its momentum in 1993 with the release of a new single, "Sigues Siempre En Mi Piel." That year, they were honored with the "Best National Rock Group" award from the Ministry of Culture, Youth, and Sports. IC also participated in the "Rock Tour."

In 1994, the band recorded its self-titled first album, Inconsciente Colectivo, at Estudio Primera Generación in Guatemala, featuring notable tracks such as "Avenida Central," "Frágil," "Amor Clandestino," "Nueva Era," and "Formas De Sentir."

Significant changes took place in 1997 when the group transitioned to a trio format with the addition of Rafa Ugarte on drums and Eduardo Carmona on bass. Despite these changes, they continued to achieve success, including the "Best Singer" award for Pato Barraza from the national newspaper "La Nación" and a recording contract with Marsol Records.

In 1998, IC released its second album, Pastillas Antidepresivas, Religiones Y Demás... Para El Alma, a double disc that included popular hits and Costa Rican rock classics like "Cautiva De Mar," "Condición," and "Se Me Puede Olvidar." The band received multiple nominations for the ACAM awards, including "Best Record Production" and "Best Composer."

The group made a notable return with the "979 Unplugged" concert, held at the Auditorio Nacional. This performance celebrated the recovery of their singer, who had previously suffered an accident that sidelined him, as well as the band's 10th anniversary. The concert was recorded and released as Inconscierto, their third album, featuring 11 live versions of significant songs and an additional previously unreleased track. This album served as a milestone in the band's career and included collaborations with other notable Costa Rican artists such as José Capmany and Luis Montalbert-Smith.

In 2001, IC signed with BMG for the distribution of their albums in Costa Rica and Central America, resulting in reissues of Inconsciente Colectivo and Pastillas Antidepresivas, Religiones Y Demás... Para El Alma, originally released in 1994 and 1998, respectively.

In 2003, the band released their final album under the Inconsciente Colectivo name, titled Data, through Marsol Records. This album addressed the theme of information overload in society and showcased a heavier sound compared to their earlier work, while still reflecting social issues in some lyrics. The single "Nunca Vencidos," dedicated to Parmenio Medina, was released from this album.

In early 2004, after significantly contributing to the national music scene, IC announced their separation, largely due to the economic challenges of sustaining their careers in Costa Rica. The members then pursued various musical and personal projects.
