Blue is the fourth studio album by Canadian singer-songwriter Joni Mitchell, released on June 22, 1971, by Reprise Records. Written and produced entirely by Mitchell, it was recorded in 1971 at A&M Studios in Hollywood, California. Created just after her breakup with Graham Nash and during an intense relationship with James Taylor, Blue explores various facets of relationships from love on "A Case of You" to insecurity on "This Flight Tonight". The songs feature simple accompaniments on piano, guitar and Appalachian dulcimer. The album peaked at number 3 on the UK Albums Chart, number 9 on the Canadian RPM Albums Chart and number 15 on the Billboard 200.

Sad, spare, and beautiful, Blue is the quintessential confessional singer/songwriter album. Forthright and poetic, Joni Mitchell’s songs are raw nerves, tales of love and loss (two words with relative meaning here) etched with stunning complexity; even tracks like “All I Want,” “My Old Man,” and “Carey” - the brightest, most hopeful moments on the record - are darkened by bittersweet moments of sorrow and loneliness. At the same time that songs like “Little Green” (about a child given up for adoption) and the title cut (a hymn to salvation supposedly penned for James Taylor) raise the stakes of confessional folk-pop to new levels of honesty and openness, Mitchell’s music moves beyond the constraints of acoustic folk into more intricate and diverse territory, setting the stage for the experimentation of her later work. Unrivaled in its intensity and insight, Blue remains a watershed.

Joni Mitchell reached her commercial high point with Court and Spark, a remarkably deft fusion of folk, pop, and jazz which stands as her best-selling work to date. While as unified and insightful as Blue, the album – a concept record exploring the roles of honesty and trust in relationships, romantic and otherwise – moves away from confessional songwriting into evocative character studies: the hit "Free Man in Paris," written about David Geffen, is a not-so-subtle dig at the machinations of the music industry, while "Raised on Robbery" offers an acutely funny look at the predatory environment of the singles bar scene. Much of Court and Spark is devoted to wary love songs: both the title cut and "Help Me," the record's most successful single, carefully measure the risks of romance, while "People's Parties" and "The Same Situation" are fraught with worry and self-doubt (standing in direct opposition to the music, which is smart, smooth, and assured from the first note to the last).

‘Mingus’, the album by Joni Mitchell from 1975 is the result of a 45-minute meeting arranged by Mingus’s wife between Mitchell, who was drifting towards a style of music jazzier than her previous output and Charles Mingus. Mingus was sadly waiting to die from motor neurons disease. Unable to play, he was bored, and his wife was keen to get him interested in something. Mingus sang the melodies into a tape recorder, chords were added by Sy Johnson, and Joni wrote the lyrics and organised the recording sessions. The band on the album were members of Weather Report. Mingus died before the project was complete. To ensure enough material was ready for the album, Joni added a song of her own ‘Wolf’. The album was cooly received by admirers of both musicians.

“Angels of Newport, let’s make history together,” [Brandi Carlile] said with growing emotion. “Hold nothing back in this moment and please welcome back to the Newport stage for the first time since 1969…. Joni Mitchell!” Mitchell emerged from the side of the stage, swaying smoothly, in fine summer-style with beret and sunglasses. Her good-natured mood instantly set the tone. This performance would be an intimate gathering of friends, not unlike the Joni Jams she’d been hosting in her own living room over the last few years of recovery. Smiling broadly, Mitchell took her on-stage seat alongside Carlile and began the extraordinary performance that was on nobody’s bingo card. Within minutes, the news had rocketed around the globe. Mitchell was back, sparkling with enthusiasm, delivering a tender and passionate set of 13 songs, ending with a joyful sing-along of “The Circle Game.”

After the expanded instrumental scale and sonic experimentation of Court & Spark and The Hissing of Summer Lawns, Joni Mitchell reverses that flow for the more intimate, interior music on Hejira, which retracts the arranging style to focus on Mitchell's distinctive acoustic guitar and piano, and the brilliant, lyrical bass fantasias of fretless bass innovator Jaco Pastorius. Known for his furious, sometimes rococo figures beneath the music of Weather Report, Pastorius is tamed by Mitchell's cooler, more deliberate ballads: these meditations coax a far gentler, subdued lyricism from Pastorius, whose intricate bass counterpoints Mitchell's coolly elegant singing, especially on the sublime "Amelia," which transforms the mystery of Amelia Earheart into a parable of both feminism and romantic self-discovery. This isn't Mitchell at her most obviously ambitious, yet the depth of feeling, poetic reach, and musical confidence make this among the finest works in a very fine canon.

Joni Mitchell was at a turning point 50 years ago. After making four acclaimed albums with Reprise Records, including her 1971 masterpiece Blue, she left the label to join the brand-new Asylum Records in 1972. Over the next seven years, Mitchell would record some of the most acclaimed music of her career while changing her musical direction by adding more jazz elements into her songwriting. The evolution culminated in 1979 with Mingus, her collaboration with jazz titan Charles Mingus, and her studio last album for Asylum.
