Extreme Ancestral Ritual by Tremor is a unique album that blends traditional South American music with experimental electronic sounds. The album features a range of instruments, including the charango, quena, and bombo, which are used alongside synthesizers and other electronic effects to create a haunting and hypnotic sound.
The album's standout tracks include "Huayrapata," which features a driving beat and eerie vocals, and "Ananku," which builds to a frenzied crescendo of percussion and synths. The album's title track, "Extreme Ancestral Ritual," is a 13-minute epic that takes the listener on a journey through different moods and textures, from slow and contemplative to fast and frenetic.
