CSN's 1969 debut not only provided the template for the era's folk-rock renaissance, but it also introduced an awe-inspiring blend of talents. Each member brought something irreplaceable to the table, whether it was David Crosby's otherworldly art-folk ("Guinevere"), Graham Nash's melodic pop perfection (the instantly hummable "Marrakesh Express") or Stephen Stills' soulful romantic laments ("Suite: Judy Blue Eyes"). And whichever way the trio turns, their goose bump-inducing harmonies are an item of natural beauty on par with a golden sunset or a forest turning auburn in autumn.
