If you take the Commerce Street bridge or Margaret Hunt Hill Bridge and head southward into Oak Cliff on Sylvan Avenue, you'll get a closeup look at the Sour Grapes Crew's handiwork on the Belmont Hotel's retaining wall, a long stretch of colorful art next to work by famed street artists Shepard Fairey and JM Rizzi. The Sour Grapes piece, fittingly, gets the most real estate. Done freestyle, it's a collection of anthropomorphized cartoon pyramids, paletas, humps and blobs with the word "DALLAS" contrasting in big white letters. It's brightly colored and feels childlike and fun yet with a bit of urban grit to it. In other words, it feels like the Oak Cliff you're about to enter.
