You all don't know how I excited I was to see Meshell at Okayplayer's featured artist. I have loved this woman since "Plantation Lullabies". She is truly talented...with thought-provoking lyrics and she's the best damn female bass guitar player I know.
As for future work, I haven't heard anything. She is still on tour and if you know Meshell's work from the past, it may be a little while before you hear from her again.
But if you are looking for other songs that she has done aside from the songs on her albums: "Plantation Lullabies, Peace Beyond Passion and Bitter", I can recommend a few sound tracks and compilation cds that she has done some fabulous songs for.
