Opus special page is here:

"Opus" is the last piano solo concert work left by 坂本龍一, who passed away on March 28, 2023, before his passing. The album includes 20 songs that Sakamoto himself chose to leave behind at the end of his life, including the classic "Merry Christmas Mr. Lawrence," songs from Sakamoto's last album "12," and "Tong Poo" from his YMO days, which was performed for the first time as a solo piano piece. Sakamoto fully trusted his crew, which included director Sorane Oh, cinematographer Bill Kirstein, sound recordist ZAK, editor Kawakami Takuya, and lighting designer Yoshimoto Yukiko. The film has been shown at the Venice International Film Festival, the New York Film Festival, and the Tokyo International Film Festival, and has become a worldwide sensation, attracting 40,000 viewers in its 10-day release in South Korea.
