"American composer Harry Partch developed a system of intonation in which the exact tuning of spectral sounds and their inversions are made possible. In Harry’s Dream, each of the thirty-three musicians are responsible for a single note played on a tuned wine glass. Each glass — tuned precisely to the (microtonal) cent — helps to build a tremendous “glass harp,” in which the listener is enveloped by a mass of sounds.

The cosmic theme, the just intonation and the unique instrumentation of Harry’s Dream, offers a complete contrast to the intimacy portrayed in Bagatellen & Studien, written for solo piano. Composed between 2007 and 2012, each of the twenty-four miniatures represents a unique style. The contrasting profile of the Bagatelles and Studies — compared to Preludes and Fugues — becomes especially clear if they are alternately performed by two pianists at two pianos, as on this recording.

Friedrich Jaecker’s paradis (paradise), written in 2013, unites both instruments, forming a delicate array of sounds mostly within the pianos’ upper octaves. The composition is thinned out — even to the point that only a single canonic line often remains. The fainted image of beauty lingers in the air, leaving one to ask if the beauty had ever been present, or in the spherical sounds simply suggested."
