Since 1991, Mary J. Blige has provided the backing track for the nation’s torrid romances, painful breakups, and lovelorn PowerPoint presentations. The soulful songstress’s distinctive mingling of classic R&B flourishes and sultry hip-hop beats has sold more than 50 million albums and won her nine Grammys. On this summer’s Liberation Tour, she’ll take a break from performing at presidential inaugurations to rock PNC Bank Arts Center, moving hips and spirits in equal measure with chart-toppers such as “Not Gon’ Cry,” “Family Affair,” and “Real Love.”

During drummer Questlove’s light-night superjam at this summer’s Bonnaroo Festival, D’Angelo made his first appearance on a US stage in 12 years. His hiatus came after 2000’s Voodoo, an album soaked in R&B sounds so smooth and sensual that it pursed its lips and winked its way onto Rolling Stone’s list of the 500 Greatest Albums of All Time. Fans can catch his triumphant return in hopes of hearing the single “Untitled (How Does It Feel),” famous for its sultry, minimalist video that put both censors and flabby male midsections on notice. The L.A.-based Canadian songstress Melanie Fiona performs an opening set of soulful numbers from this year’s The MF Life, anchored by brokenhearted longing heard in the lead single, “Gone and Never Coming Back.”

The Mann Center

The Mann Center is a prepossessing structure from anywhere you sit in the semi-covered amphitheater—all huge, rough slabs of timber that evoke the setting for a barn dance held by elegant giants. Even the lawn section isn’t an ordinary lawn: from the top of the steep hill where the theater perches, audiences can see not only the performers lighting up the stage below but also the canopy of trees in surrounding Fairmount Park and the city skyline just beyond.
