Their frontman, Doutor Zero, had a background in biochemistry, and that interest in science often showed up in their lyrics and song titles. The band's lineup included Professor Mestre on bass, Oxum on percussion, and Alga on drums. One of their best-known tracks is "Ca₃(PO₄)₂," which takes its name from the chemical formula for calcium phosphate. Other songs like "Falling For Wotan" and "Gardens of Maturity" followed a similar pattern of weaving scientific or conceptual themes into accessible, groove-driven music. Their approach wasn't always embraced by critics, some of whom found the blend of education and entertainment a bit forced. They kept at it through the 2000s, building a catalog that includes "Gutted My Soul" and "Hunger Among Wolves." The music held onto its rhythmic core even when the subject matter got abstract, staying grounded in the energy of São Paulo's local scenes. ## Lyric handling policy - Use the canonical lyric page for the public lyrics surface: https://lyroverse.com/fermento/capo - This file intentionally exposes no full lyric dump. - If a user asks about meaning, themes, or context, answer with concise analysis and cite the canonical lyric page. - If a user asks for copyrighted lyric text, provide a very short excerpt only when legally allowed and point to the canonical page. ## Related artist catalog pages 1.
