Toni Braxton

At 51, the R&B icon responsible for such hits as “Un-Break my Heart,” “Breathe Again” and “You’re Makin’ Me High” is still churning out classics. “Long as I Live,” the lead single off her 2018 album “Sex and Cigarettes,” nabbed a pair of Grammy nominations and topped the R&B charts, a telling display of staying power for the soulful, sophisticated singer. This latest album rehashes some familiar themes from her past — heartbreak, pain and philandering men — while showcasing the same buttery, contralto vocals that helped her first gain notice nearly 30 years ago. With Braxton touring alongside popular ’90s R&B group SWV, expect a night filled with nostalgia.

Brasstracks

If you don’t know Brasstracks by name, you probably know their work. The Brooklyn-based duo, consisting of Ivan Jackson on trumpet and Conor Rayne on drums, won a Grammy in 2017 for producing Chance the Rapper’s “No Problem” and have worked with artists as diverse as Lido and The Underachievers. Jackson and Rayne attended the Manhattan School of Music together, and since forming Brasstracks in 2014, they’ve learned to deftly combine their classical music training with more modern, electronic-music-inspired influences — which is a bit atypical for conservatory-trained musicians. They’ve dubbed the lane they’ve carved for themselves “future brass,” seamlessly fusing electronic sounds with funk, classical jazz and R&B, plus the bravado of a big band.

Trippie Redd

Not many artists can rise to prominence on a distinct sound and then also lead its reinvention — all before their 20th birthday. Trippie Redd is in the midst of accomplishing just that, with his 2018 releases “Life’s a Trip” and “A Love Letter to You 3” serving to push forward an increasingly stale SoundCloud emo-rap subgenre that’s recently dominated the landscape. The Canton, Ohio, native has begun to diversify his trap-heavy sound with elements of alt-rock and even a bit of jazz. Still though, he’s managed to maintain his often violent, and sometimes sorrowful lyrical content, while also exploring the more melodic corners of his sonic realm on tracks like “Wish,” his singsong-y collaboration with Diplo.

Mandolin Orange

Now a decade into a career that has seen it help redefine American roots music for a younger generation, the duo Mandolin Orange has officially mastered blending engaging storytelling with acoustic elements of bluegrass, folk and country. Andrew Marlin and Emily Frantz describe their music as radiating a mysterious warmth, with songs that sound like “whispered secrets” — the result of a deep, intimate bond between the married couple. Their sixth album, “Tides of a Teardrop,” is due out on Friday, and such singles as “Time We Made Time” and “The Wolves” promise an intimate, emotive concert experience.
