The last time we caught up with Jon Dee Graham, he was struggling to strike a balance between making a living as a traveling musician and being a good father to his young son. A quarter-century later, that son is a thriving adult living in New York City, and Graham has been dealing with the far weightier issues that come with aging. A native Texan and a fixture in Austin for decades now, the 64-year-old guitarist and singer/songwriter has survived a heart attack and a stroke over the past four years.
