Legends of Hip-Hop

For hip-hop, the South has long been a bed of innovation. Such rappers as Scarface from Houston and 8 Ball & MJG from Memphis built a foundation for entire generations of Southern artists. Juvenile, whose iconic “400 Degreez” album (the one that gave us “Back That Azz Up,” later sampled by Drake) was released 20 years ago, embodied the sound of New Orleans and rap’s regionalism. Still, few artists have been reborn in the music like Project Pat, brother of Three 6 Mafia’s Juicy J. His songs have been sampled by A$AP Rocky and, most recently, Cardi B, whose “Bickenhead” annexes his “Chickenhead.” Hip-hop has done well to keep these elders alive — all of whom will perform at this all-star revue — but what luck that they can still speak for themselves? Saturday at 8 p.m. at DAR Constitution Hall. $59-$125.

OPUS Festival

The woods of Columbia, Md., will morph into a living, breathing art exhibition at the second iteration of this fringe-pop music festival. With visual and musical artists representing 13 countries, OPUS promises something for everyone. Experimental singers Sudan Archives and Kadhja Bonet, both of whom dismantle R&B-inspired music in their own ways will perform, as will Germany’s Pantha Du Prince, a producer whose “sonic house” is an synth-driven mix of noise and glitches, and Britain’s Quantic, who culls his inspiration from around the globe. OPUS is a kaleidoscopic treat for the senses and the soul. Saturday at 5 p.m. at Merriweather Post Pavilion. Free.

April + VISTA

Lock April + VISTA in a room and they’ll make music just fine. Their songs are built around April’s delicate voice and VISTA’s lush, electronic live-producing (though April, a classically trained violinist, can contribute string work should the need arise). The D.C.-based duo creates a singular style of electro/R&B that captures the tides of life. Their heartfelt lyrics and April’s staggering voice are superimposed on VISTA’s mesmerizing soundscapes. Their yin-and-yang dynamic bursts through the music as they brew conflict and, at once, offer some semblance of peace. Oct. 17 at 8 p.m. at the Rock & Roll Hotel. Sold out.

Love, heartbreak, yearning for something more, something bigger — these are the feelings most musicians write about. Then there’s Doja Cat. She does that, too — this year’s “Amala” was filled with seductive slow jams and feel-good pop tracks — but she also makes songs inspired by cartoons (“The Powerpuff Girls”), nursery rhymes (“The Muffin Man”) and, you know, cows. The singer-rapper has been releasing music online for several years, but she went viral in August with her upload of her song “Mooo!,” complete with a video of herself twerking in a cowsuit. It engulfed the Internet, amassing 23 million views on YouTube and millions more on Twitter, and blasted her, overnight, into stardom. Even if her new fans discovered her through a viral tongue-in-cheek song, her other tunes might persuade them to stick around. Oct. 17 at 8 p.m. at Union Stage. Sold out.
