"Tár is a concept album consisting of 20 tracks, curated, composed and produced by Icelandic musician Hildur Guðnadóttir. Featuring contributions from Cate Blanchett and cellist Sophie Kauer, and performances from Dresden Philharmonic, London Contemporary Orchestra (conducted by Robert Ames), and London Symphony Orchestra (conducted by Natalie Murray Beale), the album served as the soundtrack to Todd Field's 2022 psychological drama film, Tár, starring Blanchett in the lead role as Lydia Tár.
Hildur was involved in the project after Field's persistence on the importance of the film's music and went into a three-fold process on the music production: tempo-mapping the film and characters, writing the music that Tár had written in film, and creating the actual score. The original score was recorded at the Abbey Road Studios in London, England. The album is a combination of audio glimpses from real-life recording sessions, sequences from fictional rehearsals, music listened by the film's characters and completed versions of the film's music, created by Lydia Tár in fiction. Recordings of classical pieces – Gustav Mahler's Symphony No. 5, Edward Elgar's Cello Concerto and Johann Sebastian Bach's The Well-Tempered Clavier – and non-classical compositions: the jazz song "Here's That Rainy Day" and "Cura Mente" were also included, whereas Hildur's original music acts as the centre piece of the album.
The album was digitally released under the Deutsche Grammophon label on October 21, 2022, (two weeks after the film's limited release) and was released on vinyl on January 20, 2023.[2] The score received positive response praising Hildur's composition, production and engineering. The album topped the Billboard Traditional Classical Albums from the week beginning November 5, 2022, ahead of albums released during the period by the actual Berlin Philharmonic." - Wikipedia
