Harmonica Love Affair 
I stumbled on to your blog and enjoyed the format very much.
I was the bass player at the end of Texas Storm and then along with Jimmie Vaughn, Denny Freeman, and Doyle Bramhall I moved to Austin to start STORM. I have open for or played with a lot of the blues greats.
I play the Harp now and there is a CD on CDBABY of my original songs called HILLBILLY HIPPIES. This CD has some Harp but is mostly Texas 60’s music style.
I am working on another project that will feature my harp playing more.

Thanks for the info! Don’t know if you saw it already, but I actually featured you back in 2012:

Love your style. I’m going to have to give Hillbilly Hippies a listen! Also, come back and drop me a line when you get your next project going. I’d happily feature one of your songs. Good luck with the new project!
