2

Released in 2013, '2' is the sophomore effort from Chilean metal outfit Boa. While the band is often categorized within the broader alternative metal scene, this specific record leans heavily into thrash and groove metal territories, distinguishing itself from their debut with a more aggressive, rhythmic focus. The album is characterized by its use of syncopation and low-end frequency, creating a 'wall of sound' effect that is common in industrial-influenced metal but executed here with traditional instrumentation. Critically, the album is noted for its raw lyrical themes, often touching on social unrest and existential dread, delivered in the band's signature Spanish vocals. Despite its niche status outside of South America, '2' remains a definitive example of the 'Agro-Metal' movement in Chile, blending the rhythmic sensibilities of nu-metal with the technical speed of thrash.
