Neo-soul singer Anthony Hamilton's passionate, choir-approved voice has been flooring audiences since the mid-'90s. He's used it to back up contemporaries on tracks like 2Pac's dramatic, organ-heavy “Thugz Mansion,” but his solo work is where the pipes are really let loose. They bounce along to funky synth and head-nodding bass on “Sista Big Bones,” and get low-down on the chill beats of “Day Dreamin'.” But Hamilton's velvet voice is absolutely jaw-dropping on the simmering Southern soul of fiery R&B burner “Charlene."
