Includes a booklet with photos, liner notes, and credits. Sublime private-press piano improvisations channeled by the singular figure of Willem Nyland, a Dutch-born chemist turned Gurdjieffian spiritual leader, are being remastered from the original tapes and reissued for the first time, with in-depth liner notes by Matt Marble of the American Museum of Paramusicology. A Columbia-educated chemist and self-taught pianist, Willem Nyland (1890-1975) is known as a spiritual teacher in the tradition of Greek-Armenian mystic George Ivanovich Gurdjieff, the influential spiritual teacher who developed the Fourth Way system of self-development, under whom he studied for years. In the mid/late 1960s, Nyland started his own group in upstate New York. There, after a Friday night lecture on "The Work" and a shot of brandy, Nyland would launch into remarkable piano improvisations on a specially tuned baby grand, sometimes playing for over an hour.

Each improvisation was meticulously recorded and catalogued, forming a major part of Nyland's teachings. 16 of these recordings were released as standalone LPs on Nyland's own Gage Hill Press, featuring artwork by Hungarian American decorative artist Ilonka Karasz, Nyland's wife of over 50 years. These records, with their cascading, deeply emotional playing and beautiful cover art, have become highly coveted by collectors and the specially attuned. Each contains depths of spiritual information and lyrical, almost visual instrumental storytelling. Nyland deftly and subtly shifts moods and tones throughout these truly inspired extended improvisations.

Piano Studies 337 is a particularly tempestuous performance that Nyland himself recommended to Adams as a good starting place for his music. The collaboration brings Piano Studies 337 to the world through Psychic Sounds and Nyland's family. Remastered from the original tapes and pressed to high-quality vinyl at Smashed Plastic in Chicago, the record includes extensive liner notes and faithful reproduction of the original artwork.
