Raheem Devaughn, Bootsy Collins and Cornel West in D.C. on Sunday. (Joy Freeman-Coulbary)

- The 13th (!) album by hip-hop greats the Roots will be a concept album called “undun,” and it will arrive on Dec. 6.

- Two more alt-rock bands will be getting back together. And you thought there weren’t any more left! British baggy rockers Stone Roses (“I Wanna Be Adored”) and California dream-pop faves Mazzy Star (“Fade Into You”) are both set to reactivate. Much love to both of those band’s biggest hits.
