Blue (1971) is the fourth album of Canadian singer-songwriter Joni Mitchell. Exploring the various facets of relationships from infatuation on "A Case of You" to insecurity on "This Flight Tonight", the songs feature simple accompaniments on piano, guitar, and Appalachian dulcimer. Blue was a critical and commercial success, reaching #15 on the Billboard 200 and #3 in the UK Albums Chart. The single "Carey" reached #93 on the Billboard Hot 100 chart.
Despite the success of her first three albums and songs like "Woodstock", the 1970s saw Mitchell make a decision to break from performing. After a tough breakup with her longtime boyfriend Graham Nash she set off on a vacation around Europe, during which she wrote many of the songs that appear on Blue.
