About the archive

Sonetto Classics owns the world's-largest archive of Hungarian composer-pianist Ervin Nyiregyházi: the main part of the archive was derived from the Nyiregyházi's archive from the Takasaki Art Center College (TACC), Japan.

Nyiregyházi’s personal archive were donated posthumously to the TACC in the 1990s, and the TACC added more materials over years; however, the contents of the TACC archive were not disclosed and made available to the public in the years that followed. Tomoyuki Sawado (webmaster of and his collaborator Kevin Bazzana (author of Lost Genius) made a series of attempts together to access the TACC archive in the 2000s, but were unsuccessful.

In 2012, the TACC was closed because of financial difficulties, and the archive was seized by the creditors. Negotiations to transfer ownership of the archive to Sawado were initiated in 2013, and Sawado's new company Sonetto Classics acquired the collection materials in the summer of 2016.

The sizeable collection included more than a hundred reel-to-reel tapes (including a number of masters), unpublished documentary film materials, over 2,000 compositions, hundreds of photographs, letters, booklets, music manuscripts, and more. Our first project derived from the archive, Nyiregyházi Live, vol. 1:The Century Club of California, 1972, was released on April 8th, 2017 (the 30th anniversary from his death).

Sawado's Nyiregyházi projects have been fully endorsed for over 10 years by Mattheus Smits, the president of The International Ervin Nyiregyházi Foundation in the Netherlands, which represents the Nyiregyházi's estate.
