Sumo holds a privileged place in the pantheon of Argentine national rock, both for its impact and its overwhelming musical identity. The band served as a convergence point for genres such as post-punk, new wave, reggae, and punk, blending them into a unique, highly identifiable sound that was unprecedented at the time. This film captures the soundcheck, backstage moments, and what happened on stage, achieving an unsurpassed immersive record of the last concert Sumo gave at Obras on October 10, 1987.
