At the rate they’re going, whether they mean to or not, the Most Serene Republic will alter the way in which people appreciate rock music. It might sound like a lofty achievement for an unlikely band of 20-somethings bred in the Toronto suburb of Milton, Ontario but if you pay close attention to their discography—particul arly 2007’s Population—you’ll hear something entirely unique. Don’t disregard their dense art-pop breakthrough Underwater Cinematographer (A&C 2005) or the transitional tour E.P. Phages (A&C 2006) completely; these are the keys to understanding how the Most Serene Republic came to form the masterful achievement that is Population, which might seem superficially sugary if it weren’t for the poison lurking under its remarkable layers of sound.
