Diaz's work continues to explore the visual culture and environment of South Texas and Mexico. The San Antonio-born artist often draws inspiration from renowned artists, capturing his work's "emotional essence" while simultaneously implementing his unique style, material, and politically infused themes. As a conceptual artist, Diaz creates challenging work that questions the conventions of consumerism, artistic material tradition, and the intersection of art, humor, and politics. Frequently using familiar or "low" materials and unassuming visual imagery, Diaz can convey complex ideas of culture, identity, and politics as he subverts preconceived notions of the "high" and "low." Boy on a Burro exemplifies Diaz's artistic style: conceptual, campy, humorous, provocative, and always emblematic of his Mexican American roots. With elements of Picasso-esque faces and a "make-it-yourself" sense of craft, Diaz creates a unique narrative of his artistic vision.
