In the Heart of the Moon is a duet recording by Malian guitar slinger Ali Farka Toure and Mandé lineage griot Toumani Diabate on kora. There are a few other players who contribute percussion here and there, and Ry Cooder plays a Kawai piano on a couple of tracks and a Ripley guitar on one, but other than these cats, this is a live duo set without edits or enhancements of any kind.

There were three sessions in the conference room of the Mande Hotel in Mali, the first of which was on the eve of Farka Toure being elected mayor of his town, Niafunké. Most of the music here dates back to the Jurana Kura (translated as new era) cultural movement, which was part of the independence struggle in the 1950s and early '60s. The music created by the Jurana Kura for the guitar created a entirely new style of rhythmic fingerpicking. For those familiar with Farka Toure's blazing lead style, this disc may come as a shock. While he does solo many times here, he is also playing in balance with Diabate, whose kora has the larger lyric and harmonic palette, so he is in a supporting role.

Whether the song is "Kaira" (written and performed by Diabate's father in the '50s and the earliest recorded track on the album, from before the Mande sessions), "Ai Ga Bani (I Love You)" and "Soumbou Ya Ya" (both written for young people during the Jurana Kura), or one of Farka Toure's originals near the end of the set, such as "Gomni," the style is the same. Everything echoes this earlier era because it has informed all Malian and Guinean music since. The purpose was to make people aware not only of its existence but to inspire and exhort.
