If in Peru, Los Saicos are a razor-sharp black star of the subterranean heavens, Los Holy’s are a blazing constellation. They could be considered the first local psychedelia movement of the mid-60s: they were capable of experimenting with compositions and sounds beyond the New Wave beat melodies common at the time, and all of this while remaining a basically instrumental band.

Friends from the Pueblo Libre school and neighborhood, Los Holy’s were Marcos Goyzueta (lead guitar, fuzz-tremolo), Arturo Matto (rhythm guitar), Oscar Sáenz (Hoffner bass), Renzo Carozzi (Farfisa organ), and Walo Carrillo (drums). The made their debut on the children's television programs "Locura del Ritmo" (Rhythm Madness) and "Ritmolandia" (Rhythmland).
Realizing how innovative their sound was, the label Dinsa/Suceso decided to release and produce the band's first hit, putting out their first color vinyl single, Holys Psicodélicos / Luces de Guinza (Psychedelic Holys / Lights of Guinza). It was simply an enormous hit. What followed were avalanches of letters, phone calls, their own fan club and an immense legion of followers that allowed them to launch their first tours outside of the capital, while they kept on doing “matinales” (junior concerts in movie theaters before the first screening of the day) and TV shows.

In the midst of such vivacity, the label Sono Radio, under the production and orchestra arrangements of Enrique Lynch, records the group's first LP: Sueño Sicodélico (Psychedelic Dream), an ambitious and original album, and one of the earliest and most perfect Latin American conceptual pop records. The names of the songs function as guides that lead us to cosmic and mysterious elements: "La perla sagrada" (the sacred pearl) or "Piedra de doce angulos" (twelve-angled stone) for example, which is about a unique stone crafted by Incan artisans. "Alto y Bajo" (high and low); "Choque de vientos" (clash of winds) and "Tormenta" (storm) bring the idea of basic chaos to our minds, while "Spectro I", "Alunizaje" (moon landing) and "Sueño Sicodélico" take us to the limits of fantasy and illusion to later be brought back to "Hombre Desnudo" (naked man). Conscious of having gone far and beyond, they write on the back of the LP, "Los Holys symbolize the restless and evolved heart of today's youth. Do we know all of the sounds that are heard at the bottoms of the sea? Space stations don't capture sound-waves produced at thousands of light years? We will try to reproduce those sounds with our instruments and maybe they'll end up being more pleasant than the crashing of waves."

Meanwhile, the production of singles continues, the inevitable covers of popular TV theme songs like "Hawaii Five-0" or "The High Chaparral", even other truly notable ones like, "Campo de vampiros" (field of vampires), "Sueño psicodélico", "Tema del silencio" (song of silence) or "Necio de mi corazon" (fool of my heart), this last one includes the voice of Carmen Sáenz, who sings with genuine melancholy and cool emotion.

Initially influenced by the Ventures, Les Baxter and Duane Eddy, they soon situate themselves under the syncopated funk influence of The Meters, Backyard Heavies or Lee Dorsey, curiously all bands which originate from New Orleans. Later they turn towards a kind of Latin-rooted psychedelia with prevailing guitar and organ counterpoints, all supported atop an elaborate rhythmic base.
Times change, and repression from the police turns the entire scene upside down. The band disintegrates. Later on, Walo will found additional bands, touchstones of other facets of Peruvian rock: Telegraph Avenue and Tarkus.
