Jakob Ullman's 5th solo work for piano is atypical for a piano performance, using electronic playback and requiring three assistants sustaining a soundscape to realize a concept of "gravity" that Ullman applies as laws in a conceptual soundscape modified by a series of abstract images, resulting in unexpected sonic environments, tones, timbres and momentum.

Ullman's composition of subtle gradations in sound performed very softly forcing the ear to notice the smallest variations, as realized by the string trio Ensemble Oriol Berline.

An extract from Berlin composer Jakob Ullman's 2012 3-CD box set on Edition Rz, presenting "solo III for organ" (1992/1993), an hour long work of tone and tension performed by Hans-Peter Schulz at the Big Organ in Abteikirche Neresheim.

A 3 CD box with new recordings of composer Jakob Ullmann's works, recorded between 2008-2011, including "disappearing musics for six players (more or less)", "komposition fur streichquartett 2", &c.

Between 2014-16 Jakob Ullmann composed the orchestral work "steine, feuer, sterne" (stones, fire, stars) based on a modular structure, such that individual sections can be played outside of a complete performance, solo or in predetermined combinations; this album presents one section for solo bassoon titled "Muntzers stern" performed by Dafne Vicente-Sandoval.

A work resulting from Ullmann's reflections about the relationships between music and language: language as sound and language as text, and the numerous relationships between texts of different cultural and religious traditions.
