Alpaca is a sludge doom metal band from Shanghai who formed in late 2015. Composed of four individuals from different countries (Canada, Serbia, Taiwan,China and Peru) they have become a prominent figure to emerge from the Shanghai underground music scene. Alpaca have noted Down, Eyehategod, Crowbar, Corrosion of Conformity, Red Fang, Mastodon, and Melvins as key influences to their sound. Heavy, down-tuned, bluesy guitar riffs dominate the band's repertoire. Combined with walls of feedback and tortured growling vocals, the end result creates a harsh misanthropic vibe. They have played with some the best bands Shanghai’s underground scene has to offer. They have also organized and performed in their annual SHANGHELLFEST and the bi-monthly SHANGHORRORFEST.
