45 years on the road. A long stretch playing everywhere you can imagine, rock ’n’ roll, blues, soul, simply the music he grew up with, the artists he learned from. Basically, American roots music. His band, “Rollin’ & Tumblin’,” is packed with outstanding musicians who know exactly what they’re doing. The result couldn’t be more compelling: fierce performances, songs delivered in imperative way and a songwriter with a deep collective memory. There’s no pretense in Mike Guldin’s music, it’s direct and sincerely presented, free of rhetoric and remarkably elegant. “While I Can” perfectly captures this artist’s humility toward his audience, he can achieve whatever he sets out to do and leaves the rest to less meaningful pursuits. Don’t miss this opportunity to experience truly exceptional musical instinct.
