A Drop in the Sahara

This is the first single by Interlogue, a neo-pop unit from Kyoto consisting of Mariko (Vo) and Sosuke Ogino (Key). The songs feature catchy melodies with a jazz essence. The band name Interlogue is a coined word meaning "a small story between us".
This piece was produced as the theme song for the biographical picture book "Hitotsubu no Mugi" about Yuzo Tanigaki, a Japanese surgeon who spent his entire life providing free medical care in the Sahara Desert, known as the brown nothingness.
The use of numerous percussion instruments, including the frame drum, which is said to be the world's oldest percussion instrument, as well as the djembe and talking drum, forms the world view of the vast Sahara Desert. String quartets and flutes also add color to the music.
