I have no idea of any of the bands yet for this event - but I can probably find out over the weekend.
In a very bizarre PR move, the folks that run South Texas Rock Fest didn't update their official website, opting instead for a Myspace bulletin. They also chose the biggest holiday of the year to make their announcement, so I'm scratching my head on that one. You'll notice Rock Gone Wild didn't announce any bands this week. Whatever the case, I'll post the lineup for South Texas here when it is released - or when I know the leak.
