Gronk (b. 1954) is the pseudonym of Chicano painter, printmaker, and performance artist Glugio Nicandro. Gronk was a founding member of ASCO, a multi-media arts collective based in Los Angeles which was active in the 1970s and 1980s. ASCO operated outside the boundaries of traditional art, expressing ideas and views through street theater and performance, photography, video, site-specific installations, murals, paintings and prints. While participating with ASCO, Gronk also pursued his own work in the form of drawings, paintings, and solo performances. He has become best known for his murals, but his paintings and prints have also received wide acclaim. In 1978, Gronk began keeping a kind of visual diary, a bound series of drawings which he executed daily. This diary has grown extensively, now spanning over 250 volumes. Gronk has exhibited his work throughout San Francisco, Los Angeles, Seattle, Chicago, and Paris. In 1994 he had a twenty-year retrospective exhibition at the Los Angeles County Museum of Art. In addition to his artwork, he has created set designs for theatrical productions and operas in Los Angeles, Santa Fe, and Paris and has worked with the distinguished director Peter Sellars. In 1977, he was named Artist of the Year by the Mexican American Fine Art Association, Los Angeles.
