parts: "Grief", "Anger", "Prayer" and "Salvation"; Sakamoto explained in 1998 that he was "not religious, but maybe spiritual" and "The Prayer is to anybody or anything you want to name." Sakamoto further explained: In 1998, Italian ethnomusicologist Massimo Milano published Ryuichi Sakamoto. Conversazioni through the Padova, Arcana imprint. All three editions of the book were published in the Italian language. Sakamoto's next album, BTTB (1998)—an acronym for "Back to the Basics"—was a fairly opaque reaction to the prior year's multilayered, lushly orchestrated Discord. The album comprised a series of original pieces on solo piano, including "Energy Flow" (a major hit in Japan) and a frenetic, four-hand arrangement of the Yellow Magic Orchestra classic "Tong Poo". On the BTTB U.S. tour, he opened the show performing a brief avant-garde DJ set under the stage name DJ Lovegroove. Sakamoto's long-awaited "opera" LIFE was released in 1999, with visual direction by Shiro Takatani, artistic director of Dumb Type. It premiered with seven sold-out performances in Tokyo and Osaka. This ambitious multi-genre multi-media project featured contributions by over 100 performers, including Pina Bausch, Bernardo Bertolucci, Josep Carreras, the Dalai Lama and Salman Rushdie. 2000s Sakamoto teamed with cellist Jaques Morelenbaum (a member of his 1996 trio), and Morelenbaum's wife, Paula, on a pair of albums celebrating the work of bossa nova pioneer Antonio Carlos Jobim. They recorded their first album, Casa (2001), mostly in Jobim's home studio in Rio de Janeiro, with Sakamoto performing on the late Jobim's grand piano. The album was well received, having been included in the list of The New York Timess top albums of 2002. A live album, Live in Tokyo, and a second album, A Day in New York, soon followed. Sakamoto and the Morelenbaums would also collaborate on N.M.L. No More Landmine, an international effort to raise awareness for the removal of landmines. The trio would release the single "Zero Landmine", which also featured David Sylvian, Brian Eno, Kraftwerk, Cyndi Lauper, and Haruomi Hosono & Yukihiro Takahashi, the other two founding members of Yellow Magic Orchestra, amongst nearly one hundred other performers. Sakamoto collaborated with Alva Noto (an alias of Carsten Nicolai) to release Vrioon, an album of Sakamoto's piano clusters treated by Nicolai's unique style of digital manipulation, involving the creation of "micro-loops" and minimal percussion. The two produced this work by passing the pieces back and forth until both were satisfied with the result. This
