Concord #10 is a mixed-media assemblage sculpture that is part of Miyashiro's Concord series of the early 1960s. Most of the works are composed of found religious objects juxtaposed with smooth black lacquer–painted elements. Concord is both the name of the street the artist's studio was located on and a reference to his process of assembling many disparate parts into a cohesive whole. Miyashiro attended Chouinard Art Institute, where he met Ed Bereal and Daniel LaRue Johnson. Miyashiro was also Melvin Edwards's neighbor in Los Angeles and studio mate in New York.
