Singh is the creator of hate5six, an extensive video library of punk and hardcore shows, mostly from cities across the Northeast. Singh is bafflingly prolific, often uploading videos from different cities in a twenty-four-hour period. In a subculture that thrives on spontaneity and obscurity, his collection stands out as a lovingly curated record, one that elevates shabby local bands to filmic heroes. Hardcore fans often report on social media their sightings of him at shows, as if he were a U.F.O. “It seems like he’s just always been there,” said Daniel Fang, who drums for the Baltimore punk band Turnstile and has spent many hours “drenched in sweat” with Singh at hardcore festivals. “It’s the stuff of Shaolin-monk movies, both in terms of physical endurance and a tenacious adherence to principle.”
