Thanks everyone for the greetings. Red dirt basically a subgenre of country music that got popular in the early 90s along with the alternative movement. In Texas, they call it "texas country". It's a mix of classic country, rock and roll, and grunge. It can be really alternative like Wilco, or it can be a new breed of southern rock like the Drive By Truckers, but a good blend of it all would be in bands like Cross Canadian Ragweed or Jason Boland and the Stragglers. Of course it moves into other medias like painting, photography, and the like. It was really just a way for the southwest part of the country to find its voice, that it was okay to sing grunge or pop in a southern accent without being labelled as the typical crap you would hear on a country music station. I don't consider that stuff country music, but that's a whole other story!
