Alejandro Ghersi, aka Arca (and also Nuuro), is a Caracas-born, Brooklyn-based producer of lurching, abstract hip-hop. In 2012, he issued a trio of short-form releases for the UNO label: the four-track Baron Libre, the six-track Stretch 1, and the most substantial of the three, the ten-track — but still EP-length — Stretch 2. His work caught the ear of Kanye West, who sought him to co-produce four tracks for Yeezus: “Hold My Liquor,” “I’m in It,” “Blood on the Leaves,” and “Send It Up.” That album was issued in June 2013. A month later, Arca released his own &&&&& for Hippos in Tanks, and then he maintained his profile due to heavy involvement with FKA Twigs’ self-titled EP for Young Turks. A vinyl edition of &&&&& was made available the following January. In September 2014, the single “Thievery” became Arca’s debut release for Mute; shortly after, his first full-length for the label, Xen, arrived. Arca also co-produced FKA Twigs’ 2014 debut album LP1 and Björk’s Vulnicura and Kelela’s EP Hallucinogen in 2015. Early that year, he self-released Sheep, his score for a Hood by Air fashion show that featured samples of Björk, Lana Del Ray, and Robert Wyatt in its tracks. Several songs from Sheep appeared on Mutant, a dense, challenging set that Mute released in November 2015. ~ Andy Kellman
