On Bottle It Up, Legion of Saints is able to create an intense instrumentation that immediately draws listeners in. With nuanced vocals providing considerable depth to this single, the act is able to make a bold step forward. With nods to Bloc Party and Maroon 5, Legion of Saints makes something that could just as easily work on rock radio rotation as well as the most jaded technical music fans. The tautness of the guitars, drums, and bass on Bottle It Up ensure that fans will continue to find new twists and turns even five or ten plays in. A bit of Primus at the 2:05 mark injects a boost to the song’s momentum, keeping fans firmly on the edges of their seats.
