The majority of the group was influenced by the music created by Radiohead and Fugazi. However, unlike their idols, mewithoutYou members didn’t really sing. Aaron simply read his dramatic and lyrical texts with emotion. Later the artists added music, which mixed indie-rock, emo, post-hardcore, and other genres. Such a presentation was unique and brought the group new fans.
In interviews, band members shared that the texts of some of their songs were influenced by the Christian society, The Simple Way, which helped homeless people. Aaron was impressed with the sincerity of their approach, which, according to his opinion, can’t always be found in churches.
In 2001, the band recorded its debut EP, Never Said That I Was Brave. It came out with the support of Kickstart Audio.
While performing at a Christian festival, Cornerstone, the band caught the eye of a famous label, Tooth & Nail Records.
Soon, the group signed a contract.
In a few months, Ray Taddeo left the band. Aaron took his place as a guitarist until the musicians found a replacement. Daniel Pishock joined the group.
In 2002, mewithoutYou presented a debut LP, Life. The lead single was "Bullet to Binary", which was very successful among emo music fans. After the release, many critics decided that the group had a bright future with emo style. But they were wrong. The band continued practicing different styles.
In 2003, Aaron Weiss got an offer from the band Norma Jean to record its successful single, "Memphis Will Be Laid to Waste", which became part of its debut LP.
In 2004, Daniel Pishock left the band. Greg Jehanian took his place. Next year, the group got an MTV award for being original. The band joined such successful groups as Coheed & Cambria and Dredg on their tours. At that time, many fans wanted to book mewithoutYou for private events.
In the fall of 2006, the band presented its third LP, Brother, Sister. The lead single, "Nice and Blue, Pt. 2", became popular. The producer was Brad Wood. The group members also invited Jeremy Enigk, who worked with such groups as Sunny Day Real Estate, Poor Old Lu, and The Almost.
To record Brother, Sister, musicians used two new instruments, a harp and an accordion. They bought the accordion at an online auction. It was an Italian instrument, made in 1930.
In 2007, The Hard Music Magazine called mewithoutYou the best rock group of the year. After some time, the artists finished working on a new album, It’s All Crazy! It’s All False! It’s All a Dream! It’s Alright.
In 2012, the band presented a new LP, Ten Stories. The lyrics were inspired by William James’ essay.
Three years later, mewithoutYou recorded another LP, Pale Horses. The artists returned to the hard rock, which they used in second and third LPs.
In 2018, the band’s next album, [Untitled], was released. It was followed by an EP with the same name.
