Pennsylvania-based mewithoutYou is known for their original vocal style and introspective lyrics of lead vocalist Aaron Weiss, as well as their prominent bass riffs and atmospheric guitar: all which make mewithoutYou hard to classify as any specific genre. mewithoutYou's current popularity can be attributed to their contact with their current record label Tooth And Nail Records and the release of their first two full length albums: A to B: Life and Catch for Us the Foxes. Their third full length album, Brother, Sister, was released on September 26, 2006 by the aforementioned label. They also have an EP titled I Never Said That I Was Brave, which was released in 2001 by Kickstart Audio.

The band was originally conceived as a side project. The Weiss brothers and Kleinberg were playing together in another band called The Operation (who released one album, 2001's There Is Hope for a Tree Cut Down, on Takehold Records), but Aaron wanted to start another band to experiment with new sounds. After picking up Rick Mazzotta on drums and Ray Tadeo on bass, Kleinberg and the Weiss brothers released their first EP (I Never Said That I Was Brave) in 2001 and shortly thereafter signed to Tooth & Nail Records after a show at Cornerstone Festival the same year.

Around this time Tadeo had moved on, Daniel Pishock picked up as the bass player, and The Operation disbanded soon afterward. mewithoutYou's debut full-length album, [A→B]: Life, was released in 2002. The band garnered more attention for their sophomore release, 2004's Catch for Us the Foxes, which was produced by Brad Wood (The Smashing Pumpkins, The Fire Theft). In December of 2004 Pishock had made a decision to retire as the bassist for the band and former Operation frontman, Greg Jehanian, was selected to replace him. In 2005, mewithoutYou won mtvU's "Left Field" award for most original artist. Their third album, Brother, Sister, again produced by Wood, was released on September 26th, 2006.

mewithoutYou has released videos for "January 1979" and "Paper Hanger", from Catch for Us the Foxes, with the help of Red Van Pictures this past year, and one for "Bullet to Binary" from [A→B]: Life. They have recently released a video for "Nice and Blue, Pt. 2" from Brother, Sister, directed by Shane Drake.
