Nervous Light of Sunday is a post-hardcore band hailing from Tokyo, Japan, known for their complex guitar work, introspective lyrics, and emotionally charged performances. The band, which was formed in the early 2000s, swiftly cultivated a dedicated following with their unique blend of aggressive musicianship and nuanced composition, drawing comparisons to the dynamic styles of acts like Fugazi and Shellac. Their work is characterized by its meticulous structure and the expressive, often anguished vocals that navigate the intricate soundscapes the band creates.

Following their earlier releases and growing recognition in Japan's underground music scene, Nervous Light of Sunday continued to evolve and refine their sound. Among their most recent releases, "Personality Formation" and "chain reaction" showcase their prowess in melding raw energy with tight, mathematically precise rhythms.
