I like a lot of different Texas/Red Dirt artists, but two have captured my ear recently. Amy Hughes, and her seven-song album, 45 South. It's such a unique sound. It's kind of like a combination of Jewel, Jimmy Buffett, soft rock and Texas Country.
Her best song is probably "Salty Road." But a lot of the songs have that theme of the ocean/water, which prompted me to cite the Buffett influence.
I've also listened to a lot of Kevin Fowler. Even though his Equity Nashville release didn't live up to his past efforts, I like much of KF's older stuff.
This is a video of a song from his "Loud, Loose and Crazy" album.
