Captain Beefheart - Ice Cream For Crow... (This may be botanically inaccurate but nobody can hear you being pedantic in the desert...)
Steve Roach has several but I really like Dust To Dust. Like a spaghetti western ambient album with cool guitar.
Meat Puppets "Live in Montana" I considered Meat Puppet II because it sure looks like cacti, but I'm not sure.
One of the finest Bear Family boxes, Under Western Skies, by Marty Robbins. They’re present, just in the background.
Ya Beat me To Alejandro!! ..so, I thought of who I was listening to around same time frame & ... Los Lonely Boys - Rockpango (is what fits thread) (Both of 'em great artists!!) Tex-Mex rock. They really ratcheted it up on this one!:
