Rock, blues, soul, folk, Latin music—Stephen Stills' interests run deep, his husky pipes, big sound, and fret-work pairing tenderness with toughness. His first hit, 1970's “Love the One You're With,” climbs a mountain of heated acoustic strumming with a full gospel choir behind. Boasting keys that shimmer like sun rays on the ocean and pedal steel swooping like a seagull, “Change Partners” wraps that same grandness in silky textures. Stills also expertly dips into hard rock, drawing out jams like “Rock and Roll Crazies / Cuban Bluegrass,” which is riddled with stinging licks and choppy percussion.
