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. But whether he’s targeting heads, hearts, hips or the occasional funny bone, he somehow manages to condense large nuggets of wisdom into tight little mantras, the kind embroiderers stitched onto pillows before internet memes existed.
