Tank and Leela James are on their Savage X The Soul Tour, which hits Dallas right after the Thanksgiving food coma wears off. James’ music is a testament to R&B’s timelessness; her voice carries raw human feeling. On her latest album, Did It for Love, released in March, James incorporates modern pop, too. It’s a perfect match for Tank’s music, which mixes ambient, R&B and hip-hop. This is how rhythm and blues evolves — by keeping the core the same but embracing other influences that keep it fresh. At House of Blues, Tank will play songs from his latest LP, Savage.
