The throbbing sound of synthesiser dance music owes a big debt to Ryuichi Sakamoto, 46. With two other Japanese musicians he formed Yellow Magic Orchestra in the 1970s and their massive-selling discs helped popularise technopop. Now he creates CDs and Hollywood soundtracks with a less aggressive edge, on his own and with major artists such as Youssou N'dour, Iggy Pop, David Bowie and David Byrne. He is in Hong Kong to launch Discord, an 'Enhanced CD'. In a CD player it plays music, in a computer it also offers interactive art that reflects the haunting themes. His New York concert on February 11 will be 'netcast' - broadcast on the Internet. His wife Akiko Yano is also a major recording artist. What's on your mind? The good weather and my children - I'm away from them for three weeks because of this promotional tour. Also, I'm always hearing some kind of music, some kind of sound in my mind. It won't go away. Is it difficult for you being away from all your equipment? Yes, it's very hard. Even some dreams are inspirational. So I have to be ready 24 hours, anywhere in the world. I have some music software on my PC. But I can't take much more equipment - I already have three bags. I keep thinking of telling my manager that I shouldn't do these tours. But on the other hand I do understand the necessity of doing all this. Maybe I'll give it up some day. As someone from Japan, do you find it difficult to work with Hollywood? Well, my current movie is not really a Hollywood movie. Brian de Palma, the director, is based in New York. It doesn't look like a Hollywood business to me, I just deal with Brian. I work in my studio and he comes every day to check the music. You look like a guy who likes gadgets. Yeah, little ones. Black ones. I've got a Tamagotchi, a Sony digital camera with a floppy disk drive inside, and I'm thinking of getting IBM's new laptop with a DVD drive built-in. I really like computers and gadgets. Do you ever have to think about money? If I have to think about money I'd just go to sleep. It's too stressful to me, and I avoid stress.
