Orange Pekoe (オレンジペコー) is a Japanese Jazz duo consisting of Tomoko Nagashima (lyrics, and all vocals), and Kazuma Fujimoto (guitar, composition, arrangement and programming).
The two first met through a university music club and started a band with other students, but soon broke off and started work as a duo.
They made big waves throughout the Japanese indie scene before being signed to BMG Records. Their first major label single release (Happy Valley) remained at #1 on radio air play charts for nearly two months. Organic Plastic Music sold over 300.000 copies, and reached #5 on the Oricon charts.
