The Young Lions are back! It’s always a thing to trumpet. The three-man combination of Kris Funn, Allyn Johnson, and Quincy Phillips will one day be on a commemorative coin for the new golden age of D.C. jazz, which they epitomized with their emergence in the early 2000s. Their separate careers (bassist Funn works with Christian Atunde adJuah, among others; drummer Phillips tours with Roy Hargrove; pianist Johnson is the top-call pianist in the District, a favorite in New York, and runs the jazz department at UDC) keep them from playing together nearly as often as they should. And so when they’re together on the same bandstand again, you’ve got to shout it from the rooftops. The Young Lions are back! They play at 9 p.m. at Dukem Jazz, 1114 U Street NW. Free.

Friday, September 5

It’s a Friday Night Special! At least, in the CapitalBopverse, where jazz is usually presented on the second Sunday of the month. The Jazz Loft’s stellar track-record makes every new installment something to look forward to, and when it has a special edition, you can rest assured that it’s going to be, well, special. The headlining act is the quartet led by bass clarinetist Todd Marcus, an endlessly fascinating voice from Baltimore who’s captured national attention on the jazz scene, featuring saxophonist Greg Tardy, bassist Eric Kennedy, and drummer Eliot Seppa. And as for the opener—-you’ve heard stories of great piano geniuses, the prodigies with no musical training but profound abilities to play back what they’ve heard once, with harmonic and rhythmic precision. D.C. has one, and his name is Dwayne Adell. Our Art Tatum and our Bud Powell in one. They play at 8 p.m. at Union Arts, 411 New York Avenue NE. $15.

Saturday, September 6

The first weekend in September has, lo these many 24 years, meant the Rosslyn Jazz Festival, a one-day musical adventure in Gateway Park just across the Potomac. While the Festival has been happening for all that time, it’s in recent years that it’s become something really special, a slice of cutting-edge jazz possibilities for locals—-and with free admission. And this year might actually be its best and most adventurous yet. Starting things off is Corey Wallace, a ceaselessly inventive trombonist (now based in Brooklyn after putting in time in the D.C./Baltimore territory) who founded his five-piece DUBtet with a dubstep feel, but has expanded its sound to include the full spectrum of jazz; then comes Ghost Train Orchestra, a band led by trumpeter Brian Carpenter that combines swing-era jazz (especially the sounds of the European hot clubs) with moody, cinematic soundscapes; Red Baraat, a unique fusion of jazz, groove, and Bhangra music led by percussionist Sunny Jain; and, finally, the Rebirth Brass Band, the New Orleans genre-benders that formed the epicenter of the brass band revival. Wow. The Rosslyn Jazz Festival starts at 1 p.m. at Gateway Park, 1300 Lee Highway in Arlington. Free.
