Dr. Sin

Formed in São Paulo in 1991, Dr. Sin represents a pivotal bridge in the Brazilian heavy music scene, connecting the melodic hard rock of the late 80s with the technical proficiency of the progressive metal movement.

Founded by the Busic brothers (Andria and Ivan) and guitar virtuoso Eduardo Ardanuy, the band quickly gained international attention for their high-level musicianship. Their sound identity is built on the power-trio format, characterized by Ardanuy's innovative 'shred-blues' guitar style and the Busic brothers' tight, often complex rhythmic interplay. While they are frequently grouped with Brazilian power metal acts like Angra, Dr. Sin maintains a distinct hard rock identity, prioritizing groove and traditional rock structures over symphonic elements. Their career is marked by consistent technical evolution and a brief but notable collaboration with American vocalist Michael Vescera. Critically, they are regarded as one of the most technically accomplished rock bands in South America, influencing a generation of Brazilian musicians with their blend of arena-ready hooks and instrumental sophistication.
