When it comes to songwriting, less is more, and simplicity is strength. Just ask Paul Thorn, who’s spent three decades turning soulful grooves and small syllables into songs that pack a big wallop. Maybe he learned the power of minimalism from his years as a pro boxer; maybe it just comes naturally. Thorn’s new album, Life is Just A Vapor , contains some beauties: “Life is a vapor, let’s live it while we can”; “tough times don’t last, but tough people do” (from “Tough Times Don’t Last”); “any mountain up ahead is just a hill” (from “Old Melodies”). They’re words of advice, comfort, support, encouragement, often meant to uplift, especially in times of struggle.
