Yuk. is the recording alias of Los Angeles-based experimental hip-hop producer Chad Valencia, co-founder of DJ/artist collective My Hollow Drum. His abstract sound constructions feature hazy, smudgy atmospheres and splintered beats, often incorporating found sounds and organic instrumentation. He has a strong preference for analog equipment and media over digital, and heavily uses cassette recorders in the creation of his music. After beginning My Hollow Drum in 2007 with fellow beat junkies including Teebs and Bahwee, yuk. released his debut cassette A D W A in 2010, with Matthewdavid's Leaving Records giving the album its digital release. The following year, yuk. released Of Wildermess, a digital mixtape featuring remixes and collaborations with several L.A. beat scene regulars, including Knxwledge, Devonwho, and Ras G. Yuk. appeared on scene-surveying compilations on Dublab, Stones Throw, and Dropping Gems and appeared on albums and mixes by Mndsgn and Teebs, in addition to co-founding Filipino restaurant LASA with his brother Chase Valencia in 2014. In 2015, Leaving Records released a n a k, yuk.'s sophomore album, digitally as well as on cassette and vinyl.
