were one of Peru's leading rock & roll bands in the mid-'60s, but as the decade wore on their music began to take on the influence of the psychedelic revolution, and this album suggests that in 1968 the group was beginning to walk between two worlds at once. Most of sounds like the work of a solid, no-nonsense band with tough, lean guitar work and a drummer who isn't afraid to hit, but vocalist sounds uncommonly passionate on even the most ordinary numbers, and when the band starts to hit a groove on something with a bit more drive, he lets forth with plaintive murmuring and frenetic wails that sound like the cries of a man possessed. And when really hits the top, the rest of the band seems eager to follow him, as evidenced by the wiry guitar freakouts on and the fuzzy sub- soloing on (a translated version of ). Much of is better than average Latin American rock, especially the emphatic cover of ' and the moody but it's when these guys stumble into the musical that this really becomes something special. ~ Mark Deming
