Crosby, Stills & Nash helped define the sound and soul of a generation, blending folk-rock poetry with harmony so pure it felt celestial. Formed by David Crosby, Stephen Stills, and Graham Nash, the trio became synonymous with 1960s counterculture and socially conscious songwriting, crafting music that was intimate, political, melodic, and deeply human. Their voices could ignite like wildfire or whisper like memory, carrying songs that still ripple through American music — “Suite: Judy Blue Eyes,” “Our House,” “Helplessly Hoping,” and so many more. With acoustic roots, electric expansion, and the later addition of Neil Young, CSN shaped the blueprint for modern harmony-driven rock, leaving a legacy that continues to resonate across generations, festival stages, and every listener who ever found truth in three voices singing as one.
