For more upbeat stuff, let me offer up a singer by the name of Adrian. One name, working cowgirl, great voice, huge raw talent.
http://www.buckaroogirl.com/Home.html1st CD demonstrates that raw talent, incredible vocal range, and sings about things that are close to me - Drifting Vaquero, Elko, and especially Will James Days. Her 2nd CD was produced by the singer/songwriter Tom Russell, and he worked to channel her talent, diminishing the impact somewhat, but also producing some excellent tunes - Damn Rodeo Men, Red Dirt Girl and Farewell Angelina.
She's be a good tie-in for CAS-related podcast or just to get things rolling.
