Traversing a period from Blue (1971) to her 2007 album Shine, this four-disc, artist-curated boxed set contains some of the greatest songwriting of the last 40-plus years. Subtitled ‘A Quartet, A Ballet, Waiting to be Danced’, Love Has Many Faces was initially conceived as the music to a ballet that was to evoke Mitchell's vision of love. The ballet project was subsequently shelved, but what remains is this stunning compendium of 53 newly remastered songs, themed around the presence (or absence) of love in four separate acts. Not a conventional ‘Best Of’ then there's no ‘Big Yellow Taxi’ or ‘Woodstock’, for example, although many of Mitchell's best-loved songs certainly do feature. From early masterpieces such as ‘All I Want’ and ‘River’ (from Blue), ‘Just Like This Train’ (from Court And Spark) and ‘Shades of Scarlett Conquering’ (from The Hissing Of Summer Lawns), to later songwriting jewels such as ‘Stay In Touch’ (from Taming The Tiger) and ‘Love’ (from Travelogue), the singer-songwriter's startling originality strikes you at every turn: from her use of alternative tunings and singular harmonic approach to the music's remarkable rhythmic fluidity and emotional charge. There have been some terrific Mitchell songbooks released over the past decade, including Ian Shaw's 2006 album Drawn To All Things, Herbie Hancock's 2007 Grammy Award-winning River: The Joni Letters (on which Mitchell sang ‘Tea Leaf Prophecy’) and Tierney Sutton's similarly Grammy-winning 2013 album After Blue. Encompassing folk, pop, rock and jazz, hearing the source material makes you appreciate anew the tentacular reach of Mitchell's influence. Annotated and designed by Mitchell herself, and presented as a stylish hardback book, this is genius in quadruplicate.
