"I do not exist," mewithoutYou front man Aaron Weiss mutters to open the bands third full-length, 'Brother/Sister', setting the tone for an album that explores philosophical, spiritual and interpersonal relationships with equal aplomb. However, while Weiss has become known for his stream of consciousness lyrics communicated via his half-sung/half-shouted vocals, 'Brother/Sister' is a huge progression for Weiss personally, as well as the rest of the Philadelphia-based band. Oh, and it also has the potential to finally break the underground's best kept secret wide open. In a musical landscape dominated by genre divisions and marketing campaigns, 'Brother/Sister' is simply an album made by five people who create art without any limitations - and that's what makes it so important.
