Harpy or Wono Satoru

Hello, i bought the book + cd "Japanese Independent Music" the other day. There are two tracks on it, which i like very much, Wono Satoru "Allegro" on Kaeru Cafe and Harpy "Slash". Would anybody know a site where i could order albums by them, preferable in europe, I tried some japanese websites, but unfortunately my japanese reading abilities are zero. arthur
