You may have heard Lee Bob’s beautiful cover of Nina Simone’s 1968 classic “Peace of Mind,” but he’s also a singer who writes his own songs. You’ll find that cover on his new EP, Free, alongside an intimate collection of songs conceived on a rooftop in Bamako, Mali. We’re sharing the title track, on which you can hear a kaleidoscopic integration of different genres, from folk ballads to Malian polyrhythms.
