Houston has exploded with street art in recent years, not with unsightly tagging but elaborate, bold works of all sizes. Lately that trend has even extended, somewhat controversially, to many electrical utility boxes around town. But first there was "Houston Is...," the vivid, borderline psychedelic mural sprawling across the southern wall of venerable Market Square eatery Treebeard's. A collision of red, yellow, orange, green and purple (naturally) anchored by the skyline and "HOUSTON," the painting naturally draws the eye to the well-chosen words "inspired," "hip," "tasty," "funky" and "savvy." Created by Gonzo247, founder of the Aerosol Warfare gallery and the Graffiti & Street Art Museum of Texas, "Houston Is..." reflects a turning point of sorts for Bayou City public art: Gonzo created striking murals before, and many since, but here his patron was the Greater Houston Convention and Visitors Bureau, producers of a recent TV spot in which the mural co-stars with Gulf Coast Soul musicians The Suffers. In other words, as seen by "Houston Is...," the arts are front and center in Houston's public-image strategy. Good call — "City of Street Art" has a nice ring to it.
