Young Dolph and Key Glock

Young Dolph has spent the past decade burgeoning his bona fides as the king of Memphis rap with a steady stream of gruff-voiced, syrup-slow gangster tales. In the past few years, he’s had some competition for the crown in Key Glock, a 22-year-old talent with a similar flow and an ear for equally menacing trunk-rattlers. Thankfully, the two rappers (who are also cousins-by-marriage) have decided to join forces, releasing the collaborative “Dum and Dummer,” hitting the road for the No Rules Tour and aiming to be rap’s next best duo. As Dolph raps on the mixtape, “We on some UGK s--- right now, boy, ain’t nobody triller.” March 1 at 8 p.m. at Fillmore Silver Spring. $29.50.

Om

Originally an offshoot of Sleep — the stoner metal band infamous for its hour-long, one-song album “Dopesmoker” — San Francisco trio Om has always pursued higher purposes. Fronted by singer-bassist Al Cisneros, Om has brought Tibetan and Byzantine chant structures and religious iconography to doom and drone metal. And while its first albums explored maximalist scale through minimal means, the group’s past two albums, 2009’s “God is Good” and 2012’s “Advaitic Songs,” have added strings, woodwinds and additional production to the mix, taking the band to an even more biblical level. March 2 at 7:30 p.m. at Black Cat. $20.

Aventura

At the turn of the millennium, Bronx boy band Aventura revolutionized bachata — the bitter, bluesy Dominican sound — going electric and infusing the genre with R&B, rap and rock. They spent the aughts releasing a string of hits and crossing over by collaborating with the likes of Ludacris, Wyclef Jean and Akon. In the years since, frontman Romeo Santos achieved solo success, but after reuniting for a song on his most recent album and a handful of one-off gigs, the group is going back on the road for its first tour since going on hiatus in 2011. March 3 and 5 at 8 p.m. at Capital One Arena. $39.50-$179.50.

Lil Tjay

“My whole life I wanted something more,” Lil Tjay told Pitchfork last year. “I didn’t get here just to be broke at 28.” To that end, the 18-year-old rapper has big plans — including vocal and dance lessons so that he can be the next Usher. But for now, he’s embracing his “Bronx Justin Bieber” nickname, infusing his songs with youthful melodies that juxtapose the world-weary melancholy of his lyrics. “I was stuck up in the streets, but I had a brain,” he raps on his biggest hit, “F.N.” “. . . All I ever wanted was to have a name.” He’s quickly on his way to establishing one. March 4 at 8 p.m. at Fillmore Silver Spring. $33-$125.
