Singer Cody ChesnuTT often gets lumped into neo-soul with other contemporary crooners, but his music doesn’t belong in one specific cage. The Atlanta native is still perhaps best known for his appearance on the Roots’ “The Seed (2.0),” a reworking of “The Seed” from his 2002 debut The Headphone Masterpiece. Both tracks show off ChesnuTT’s intricate guitar-playing and smoky voice, which have become his musical calling cards. But over the last decade, he’s expanded his sound, moving from rougher rock to something more mellifluous: On 2013’s “Til I Met Thee,” he delivers the first verse a cappella before brass and percussion lift the funky romantic ballad, accentuating tender lyrics with high-pitched vocal runs. In addition to his trademark bits of love advice (on “Love Is More Than a Wedding Day,” he reminds listeners that “you can’t walk away when it gets a little heavy”) ChestnuTT will bring his joyful tone and charm to the Howard Theatre for an eclectic show that will warm the spirits of the lovers and the lonely alike. Cody ChesnuTT performs at 7:30 p.m. at the Howard Theatre, 620 T St. NW. $20–$25. (202) 803-2899. thehowardtheatre.com.
