This band was formed in August 2005 in Bangkuntian, Thailand. Vocalist Peerasit Poltan, guitarist Chatchai Ngamsirimongkhonchai, second guitarist Piti Estrellado Sahaphong Dane Dominic Chicco, bassist Thongake Horsiritham, synthesizer Martsamrit Pasupa and drummer Chandej Worngsatthanaphong all knew each other from university. Coming from different music background, these nerds have put their input together to create their unique band's sound. By late 2005, Lomosonic joined Smallroom Records, and under P Roong guidance, they start to work on their album. In December 2008, Lomosonic have gathered enough materials to make a proper record. In late April 2009, Lomosonic recorded 10 tracks and release their first album, Firework, under Smallroom Label.
