Here’s a great introduction to Jun Mayuzumi’s work. This Live performance LP shows her talent through a variety of singing styles. Rhythm and Blues, Bossa nova, Soul and Kayokyoku. Backing her is the inevitable Akira Ishikawa on drums and a big name in Japanese jazz at the time : Nobuo Hara & His Sharps and Flats.
Listen to “Yagi Bushi” for a taste.
