Of the countless accolades and analyses that surround Blue, no point is more significant than the fact that the 1971 Joni Mitchell album continues to become more popular, revered, referenced, and relevant with each passing day. Such vitality is not only extremely singular; it is the ultimate measure of great art and, in the context of Blue, indisputable proof of the record’s accessibility, integrity, and timelessness. If the most brilliant and everlasting music seeks to find truths shared by all of humanity, Blue can be said to be universal doctrine.
