Project46 is a heavy metal band from São Paulo, Brazil. Since forming in 2008 by guitarists and childhood friends, Jean Patton and Vinicius Castellari, the quintet has released one E.P. and two full-length albums and have played several large rock and metal festivals in and around Brazil and South America. Known for their politically and socially controversial lyrics, Project46’s popularity outside of Brazil has been steadily growing and as of summer 2015 could be heard on American satellite radio, with Sirius XM's Liquid Metal channel playing the first track “Caos Renomeado” from their 2014 album, Que Seja Feita A Nossa Vontade.
Project46 played at the 30th anniversary of Rock in Rio, September 24, 2015 in Rio de Janeiro, opening for Halestorm, Lamb of God and Deftones.
