Okay, we're cheating here. Obviously you can't buy -- in the traditional sense of the word -- CDs at this Web site. What you can do, however, is find MP3s of local and regional bands, then with a few mouse clicks, make a purchase. The site is essentially an MP3.com for Houston acts, but better. It's Houston-based, run by ex-local band geek James Lewey, who knows his shit, and also provides for the sale of T-shirts and other assorted local band paraphernalia. Participating bands, which number about 100 at this point, don't have to worry about huckster surfers logging on and absconding with MP3s. Lewey gives away only about half of every song -- just little samples. Surfers who are enticed and crave an entire meal need to whip out their credit cards. The future of local music commerce is in our backyard.
