Americana, for all intensive purposes, is roots based music. Sounds, songs, and stories are as much a part of the region as they are apart of the artist. Although the Americana generally adopts regional sounds and sub-genres and provides a platform with a wider national and international reach, we have to wonder what we as listeners might be losing when not defining a song or a band by where it/they comes from. Geographically where does Americana start and better yet.. where does it end? 
Cody Canada, formerly of "Cross Canadian Ragweed" and currently of his new band Cody Canada & The Departed"- is a poster-child for the sub-genre known as Red Dirt Country. A form of music developed between Oklahoma and Texas that generally mixes rock and roll-based sound with country-style songwriting.
