On a cold Wednesday night in Austin, Texas, Jon Dee Graham nestles into a floral print sofa with his son, William, performing with him. Hugging a guitar, he thanks the few dozen Facebook Live viewers whoâve been listening. He shouts, he laughs, and he sings of moonlit skies and Amsterdam sunshine âsweeter than Van Gogh yellow.â But itâs all bittersweet. The past year has been a shadow of the musicianâs normal life. He starts his livestream at 7 p.m. every Wednesday. Thatâs when, for almost 25 years, heâs taken the stage at The Continental Club â the same stage where, for $2, he would hear Stevie Ray Vaughan.
