O'Connor is an enduring figure within the Argentine rock scene, known widely for its heavy metal and hard rock influences. Originally formed in 1998 by vocalist Claudio O'Connor after his departure from the legendary band Malón, O'Connor has consistently provided a powerful outlet for its frontman's distinctive voice and socially conscious lyrical style. Their music is characterized by strong riffing, relentless rhythms, and a penchant for exploring political and social themes within their songs.

Over the years, O'Connor has built an extensive discography, punctuated by albums such as "Yerba Mala Nunca Muere" and "El Tiempo Es Tan Pequeño," which showcase the band's ability to fuse traditional heavy metal with elements of Argentine rock. Their more recent releases, such as "La Grieta" and "Ana no duerme," illustrate the band's dedication to evolving their sound while maintaining the hard-edged rock for which they are known. "Un lugar que nunca muere" (Vols. 1 and 2) serve as a testament to the band's longevity, demonstrating their sustained relevance in the rock genre. With a career that spans over two decades, O'Connor continues to be a pillar in Argentina's music scene, delivering powerful performances and a catalog of work that resonates with audiences both old and new.
