There's not much to it, really. In fact, NTXshowlist is solely what its name makes it out to be: a Web site that does nothing but display each day's concert listings, offering up gigs from touring and local acts alike. But, in today's convoluted, Flash-driven and commenter-ruined Internet age, the site, run by Gutterth Productions' Michael Briggs and Brent Frishman (who are also maybe the two biggest music fans in the entire region), the site's biggest strength is its simplicity. There are no pictures, no descriptions of the shows, and no critiques of the bands playing. Again: It's. Just. A. List. Here's how it works: Briggs and Frishman, ever-attentive watchers of the local scene, keep an eye on each venue's upcoming calendars, compile them into one place and add in the shows that their readers send their way. And that, an incredibly simple but undeniably useful tool, is all it needs to be.
