Leni Stern’s new single, “Fonio,” is named after a delicious grain found all over Africa that is a staple of Senegalese cuisine. It is also featured in the guitarist/vocalist/producer’s forthcoming album, Dance, as one of the songs of its joyful, multilingual set, colored with a blend of international rhythms. Dance will be released on June 4 and sees her fronting her cross-cultural New York quartet with Argentine keyboardist Leo Genovese and the rhythm duo of bassist Mamadou Ba and percussionist Eladji Alioune Faye, both originally from Senegal.
