Since she was a teen, singer and bassist Esperanza Spalding has been intoxicating listeners with her dreamlike vocals and innate talent for playing any instrument she encounters. Berklee-educated, in 2011 she was the was the first jazz musician to earn the Grammy Award for Best New Artist. Earlier this month, Spalding released a new track every day for 12 consecutive days, culminating in the album _12 Little Spells_ — each track (or spell) is a mini-exploration into the mysticism of the human body and the power of healing, and is accompanied by visuals highlighting specific body parts. Sonically, these studies on spirituality manifest in the form of woozy loops and layers dappled with tense bass jabs. Today, Esperanza Spalding joins Vivian to talk about spell casting, frequencies and visions.
