I'd have to highly recommend Gretchen Peter's album, "One to the Heart, One to the Head." The entire 15-song collection is theme-based around the American west. Also "Culture Swing" by Tish Hinojosa. Throw in some of the soundtrack from "Pat Garrett and Billy the Kid." And the soundtrack from "Lone Star." Maybe some of the haunting instrumentals from the film "Country." And the soundtracks from "Legends of the Fall," "A River Runs Through It." "The Education of Little Tree," and "All the Pretty Horses." And The album "Comes a Time" by Neil Young.
