Bomrani was founded in 2008 by Behzad Omrani (singer and guitar player). After working as a solo artist (using “Bomrani” as his stage name) and recording Yellow Sky, Blue Sun in 2010, Mani Mozaka (harmonica and trumpet) and Jahanyar Ghorbani (electric guitar) joined him. The Bomrani trio gave several experimental performances in smaller venues before Arash Omrani (keyboards), Kiarash Omrani (bass) and Abtin Yaghmaeian (drums) joined them. The songs they wrote before 2011 were collected in an album called Naked Socks. After performing in various charity shows in 2012, they gradually started to gain momentum and were recognized by various cultural circles, which led to several collaborations with reputable Iranian theater directors. They were cherished as the most hard-working band in theater music in 2012 by the public relations of the prestigious City Theater of Tehran. In 2012, they were commissioned by Chekeh Records to make a children’s album. The favorite Red Bus was the result, released on June 2014.
In 2014, which marked their first appearance on Iranian National TV, the band started recording its first official studio album Common Vent, released on May 2015. Bomrani performed Common Vent in Azadi Concert Hall in eight nights in the summer of 2015. Shortly after that, they started writing material for their next album, Leaving and Passing By, released in early 2017. This album received considerable attention shortly followed by successful concerts in the same year. Since 2016, the band started giving numerous successful performances across Europe.
