San Antonio-born Walt Wilkins has been called a genius, more than once, and a writer the caliber of John Steinbeck and his voice as comfortable as a pair of old blue jeans, and he is, and has, all of that. His crafting of story-songs, hard-edged vocals to sing them and a plaintive guitar have made him a fixture of the Texas music scene (and Nashville before that). He’s put his magical touch on recordings by new and veteran artists, too many to count.
