This is what we found on Wikipedia regarding the Armor For Sleep:

Armor for Sleep is an American rock band from Teaneck, New Jersey. Their original lineup consisted of vocalist, guitarist, and songwriter Ben Jorgensen, lead guitarist PJ DeCicco, bassist Anthony DiIonno and drummer Nash Breen. Currently, the band consists of Jorgensen and Breen alongside lead guitarist Erik Rudic and bassist Chad Sabo, both members of the Cold Seas, in which Breen is also a member.

After initial demos had been distributed, New York–based independent label Equal Vision Records signed the band and went on to release the concept-based albums, Dream to Make Believe (2003) and What to Do When You Are Dead (2005). The following year, the band signed to Sire Records and Warner Bros. and released their last album Smile for Them (2007) before a yearslong hiatus. The band announced their disbandment in October 2009, only reuniting briefly for tours in 2012 and 2015. They officially reunited in 2020 and have since released two more albums, The Rain Museum (2022) and There Is No Memory (2025).

During their recording career, the band has been known for their blend of alternative rock, atmospheric emo, and dream pop, as well as their "emotionally charged" lyrics.
