Organised Delirium is pianist Tamara Stefanovich' personal exploration of the sonata form, centred around Boulez' Piano Sonata No. 2 which she studied in close collaboration with the composer, reigniting her passion as a performer. Boulez' Piano Sonata No. 2 represents a restructuring of music after it's destruction during World War II. Boulez' iconoclast piece is paired with twentieth-century sonatas by Eisler, Bartok and Shostakovich, each questioning the use of the term 'sonata', while the programme closes with a return the sonata's origins by way of Domenico Scarlatti. Appearing in the context of Boulez' centenary, this adventurous album reveals a strong kinship to Stefanovich' PENTATONE debut Influences (2019), and deepens our understanding of the sonata, it's history and it's many shapes. The New York Times lauded Tamara's recent concert performance of Boulez' Piano Sonata No. 2, stating that "Ms. Stefanovich's performance was staggeringly brilliant". Praised by The Guardian as "fearless, dazzling, exceptional", Tamara Stefanovich is one of today's most adventurous and sought-after pianists. After Influences (2019), Visions (2022) and Nicolaou: Etudes & Frames (2023), she now releases her fourth PENTATONE album.

Domenico Giuseppe Scarlatti (1685-1757) devoted himself to a single form like no other composer before him. The more than 550 mostly single-movement sonatas for the harpsichord influenced numerous composers throughout the ages, from his contemporary Johann Sebastian Bach and Frederic Chopin to 21st-century artists such as Georg Katzer. The four selected sonatas K 27, K 213, K 247 and K 268 represent only a small selection of his immensely varied oeuvre and yet they illuminate all the different aspects of his extraordinarily creative composing. Scarlatti himself modestly described many of his sonatas as "Essercizi per gravicembalo". His sonata works contain every conceivable technical challenge, as he himself was one of the most sought-after and virtuoso harpsichordists of his time. Georg Katzer (1935-2019) composed the Five Miniatures in 1971. They are primarily to be understood as gestural music. Although the playing technique is traditional with a few exceptions (the use of the elbows or rolling hands), the miniatures reveal a wealth of ideas in musical forms of expression that evoke the most diverse sensations in a short space of time and space. The work Due to my admiration for D.S. was composed by Georg Katzer in 2001. The close relationship between Fanny Hensel (1805-1847) and her brother Felix Mendelssohn encouraged both siblings throughout their musical careers. And yet, throughout her life, Fanny Hensel fought for even remotely similar recognition of her extraordinary talent as a pianist, conductor and composer. The Four Songs for Pianoforte, Opus 2, are among the few works published by Bote & Bock in 1846 during Fanny Hensel's lifetime.
