Stills’ “Suite: Judy Blue Eyes,” “Carry On/Questions,” and “49 Bye Byes” places CSN’s scintillating voices amidst intricate arrangements with folk, country and Latin undertones. Crosby adds a mystical element with dreamy tunes like “Guinnevere” and a political bent with “Long Time Gone.” Nash proves himself a master of wistful, sweet-toned pop with “Our House,” “Just a Song Before I Go,” and “Wasted On the Way.”
