Divine Horsemen is a good call. They were'nt that popular in their day , but , they put on a GREAT show. Their singer was Chris D. From The Flesheaters , and their Bassist , Robyn Jameson from the same band (a version of the band.), and their early Guitarist was Cam King of The Explosives , Roky Erickson's primary band , tho' not anymore.....Their other singer , Julie Christenson, was married to a member of The Conqueroo before she married Chris D.
They combined Country with traces of Punk and even Metal , not as The Flesheaters did , tho' , it was far more subtle....
If you like the Texas Psych oriented stuff , I URGE you to check out Cold Sun , an early - mid 70's "Psych when you could'nt give it away" band , very dark , led by Bill Miller, who later went on to Roky Erickson and The Aliens. It's some mindbending shit , but , it won't come cheap.
