Joan Shelley. Kentucky folksinger whose becalmed presence will ring bells for fans of trance-inducing vocalists such as June Tabor and Sandy Denny. Shelley's self-titled latest, on the No Quarter label, is (minimally) produced by Wilco's Jeff Tweedy, and features his son Spencer on drums and guitarist James Elkington. Tuesday at Boot & Saddle.

Robert Glasper Experiment. At the onset of ArtScience, the 2016 album credited to the Robert Glasper Experiment, the jazz-plus-so-much-more pianist says: "The reality is my people have given the world so many styles of music … so why should I confine myself just to one?" He doesn't. With Spank, the trio led by Philly drummer George "Spanky" McCurdy. Tuesday at World Cafe Live.

The War on Drugs, "Holding On." The second song to be released from the Philadelphia band's forthcoming A Deeper Understanding features a moving Brett Haley-directed video from a concept by Jessica Jones actress Krysten Ritter starring Frankie Faison — yes, that's Commissioner Ervin H. Burrell from The Wire. A Deeper Understanding is out Aug. 25.

Neil Diamond. The "Jewish Elvis" has been busy making Christmas albums of late. But expect this 50th-anniversary tour date to be a cavalcade of hits, performed with more brio than you'd have any right to expect from a 76-year-old man. Tuesday at Wells Fargo Center.

Chastity Belt. The Walla Walla, Wash.-formed and Seattle-based female indie pop quartet that showcases the catchy songs of leader Julia Shapiro on the earnest and dreamy new I Used to Spend So Much Time Alone. Also worth catching: Sneaks, the one-woman project of D.C. songwriter Eva Moolchan. Thursday at PhilaMOCA.
