The perfect bricks-and-mortar store to buy local CDs does not exist. If you wanted to stock everything this city has come up with and continues to churn out — folk, zydeco, hip-hop, blues, rock, jazz, punk, R&B and country — you'd need a store as big as the Astrodome. (Hmm, now there's an idea...) In the absence of that H-Town music pleasure dome, Sig's will do nicely. Not only do owners Thomas and Jennifer Escalante stock a wide variety of historical Houston music in both LP and CD format, but they also have a generous policy of taking in product from the locals of today. "They bring it in, we put it on consignment," Thomas Escalante says. "Our policy is real simple." What's more, Sig's is one of the only stores that attempts to brand Houston's image — it takes its name from a book by Sig Byrd, the legendary chronicler of gritty Bayou City street life from the old daily Houston Press.
