Even though it's been widely ridiculed — and hated — it's hard to deny the power of Luis Jimenez's "Mustang" on the approach to Jeppesen Terminal at DIA. The 32-foot-high outdoor piece is a perfect example of the artist's sensibility, bridging the gap between the high art of classic Western imagery and the low brow of the carnival's garishly painted fiberglass ornaments. The gigantic rearing stallion, with its luridly blue coat, bulging black veins and glowing reddish-orange eyes, is pointedly disturbing, and the story of its creation matches that mood. Thirteen years overdue when it was delivered in February, "Mustang" was also over budget and the subject of lawsuits between Denver and Jimenez. And in June 2006, a piece of the sculpture fell on the artist and killed him. Nonetheless, Jimenez's final work may have been his best.
