Percy Faith recorded two albums of music by Japanese composers Masao Koga and Ryoichi Hattori. Both were released in Japan. My pressing of Koga Melodies was from CBS in Holland. For Koga Melodies, Faith won a CBS award for "Best International Project."
Koga and Hattori were likened to, perhaps, Cole Porter and Richard Rodgers (this doesn't quite work, they were more contemporary). They wrote tunes that Percy Faith felt would be challenging to arrange in his style (with all the countermelodies and ideas that Faith added to the compositions of others). The liner notes of HATTORI indicate that Hattori was quite stunned at the complexity and richness that Faith brought to his work. Kats indicates that Koga is available on CD in Japan, I'm still trying to find out more. The late Yukio Tanase lobbied hard to get the two albums reissued by CBS/Sony as a "2 on 1" CD years ago, but it never happened.
