Emerging in the ‘90s as a power trio in Buenos Aires, Argentina, Catupecu Machu quickly solidified a reputation within their homeland's avid rock culture for their energetic live performances, enhanced by an innovative use of surround sound. Hard, metallic guitars are propelled forward by a relentless rhythmic head-charge as lead and harmony vocals weave melodic threads, softening the musical onslaught just enough to encourage audience participation. And rather than slowing down as the accolades accumulated, the band remained vital and unpredictable in live performance.
