All That Jazz was originally a temporary group commissioned by Studio Ghibli to create jazz-style covers of soundtracks from Japan’s Studio Ghibli animated films. They went on to make covers of popular Japanese music and anime theme songs. Much of the band’s music is purely instrumental, but COSMIC HOME's Yuriko Kuwahara (桑原由里子, クワハラユリコ) and Naomi Hattori (服部直美) provide vocals on many tracks. Only Kuwahara sings on the Studio Ghibli covers, while their other covers feature both Hattori and Kuwahara.
