In the years since John Prine inadvertently defined Americana in 1974 with his debut album, which showcased insightful, poetic storytelling in songs like “Sam Stone” and “Hello in There,” his stature has only risen. Like Dylan’s, even Prine’s minor albums harbor worthwhile chestnuts, but lately they’ve been all gold. Fair & Square, his last of original songs, won a Grammy, an award everyone knew was partially retroactive for his heavily influential back catalogue. Live, Prine plays with only a bassist and guitarist, and his stunning poetry and wry demeanor turn the hardest hearts into lifelong fans. He plays Wednesday, June 8, at the Uptown Theatre. 1350 Third St., Napa. 7:30pm. $55–$65. 707.259.0333.
