The Skinny: Rooftops take its brand of intricate math pop and layer it generously with acoustic guitars, horns, strings and percussion. The resulting arrangements create an impressive sound uniting math rock and post rock into something bold, new and exciting. The band adds vocals to the mix only sparingly but at brilliantly timed intervals for maximum effect. It is the bold, unbridled enthusiasm of math rock harnessed only by the restraints and subtle nuances of post rock. A Forest Of Polarity is the sound of two becoming one. Can you hear it?
