HYDE will digitally release his new song "NOSTALGIC" on June 25.

The song's release date is also the first day of his orchestra tour '20th Orchestra Tour HYDE ROENTGEN 2021' which is a reproduction of his first solo album "ROENTGEN." It's said to be a song portraying a "quiet" worldview featuring HYDE's powerful yet sorrowful vocals with the piano and strings in the background. The jacket cover was photographed by art director and photographer Mote Sinabel.
