21 Transparencies is based on transparencies that Jonas Wood drew on over the past 10 years. In his practice, Wood often draws on transparencies before projecting and tracing these drawings onto paper, canvas or linen. This process allows him to first simplify images into less complicated shapes, and then reassemble them into new compositions.

Wood has been the subject of solo exhibitions at the Dallas Museum of Art (2019); Museum Voorlinden, Wassenaar, the Netherlands (with Shio Kusaka, 2017); Lever House, New York (2014); and Hammer Museum, Los Angeles (2010). Other solo projects include Still Life with Two Owls, a monumental picture covering the façade of the Museum of Contemporary Art, Los Angeles (2016—2018); Shelf Still Life, High Line Billboard, High Line Art, New York (2014); and LAXART Billboard and Façade, LAXART, Los Angeles (2014). He lives and works in Los Angeles.
