SATURDAY

Pentatonix

How many groups can say they owe their career to Nick Lachey? Well, OK, to the Lachey-hosted show “The Sing-Off,” which this impressive vocal quintet won in 2011. Now, they’ve won a Grammy Award, earned a platinum Christmas album (“That’s Christmas to Me”) and last year released “PTX, Vols. 1 & 2,” a collection of original songs and their creative covers of pop hits such as “We Are Young” and “Radioactive.”

8 p.m. March 21. Sold out. The Tabernacle, 152 Luckie St., Atlanta. 1-800-745-3000, livenation.com.

Joe Ely

The master of Texas honky-tonk made music headlines at the end of 2014 when a duet with Linda Ronstadt, “Where Is My Love,” was unearthed after more than 25 years and was released on iTunes. The guitarist also has stayed busy with the release of his debut novel, “Reverb: An Odyssey,” a coming-of-age story set in Ely’s hometown of Lubbock. Ely last released an album in 2011, “Satisfied at Last.”

8:30 p.m. March 21. $35 (advance), $42 (at the door) and $175 (reserved table of four). Eddie's Attic, 515-B N. McDonough St., Decatur. 1-877-725-8849, ticketalternative.com.

SUNDAY

George Winston

The skilled pianist is known by many for his 1996 album, “Linus and Lucy — The Music of Vince Guaraldi,” dedicated to the theme music Guaraldi wrote for the “Peanuts” cartoons. But Winston, who has been tickling the ivories professionally for 40 years, also has tinkered with the music of the Doors (2002’s “Night Divides the Day — The Music of the Doors”), country and blues. In addition to piano, Winston plays harmonica, acoustic guitar and Hawaiian slack-key guitar.

7:30 p.m. March 22. $30 (advance), $32.50 (day of the show). Variety Playhouse, 1099 Euclid Ave. N.E., Atlanta. 1-800-745-3000, ticketmaster.com.

TUESDAY

Ariana Grande

The Honeymoon Tour is only the second road jaunt for the “Break Free” pop phenom. But it’s been a big jump from starring in Nickelodeon’s “Sam & Cat” to racking up awards and sharing stage time with Nicki Minaj and Little Big Town, so why not add arena headliner to the list? After traversing North America through April, Grande will head to Europe, tagging this as her first world tour.

With Rixton and Cashmere Cat. 7:30 p.m. March 24. $29.50-$69.50. Philips Arena, 1 Philips Drive, Atlanta. 1-800-745-3000, ticketmaster.com.

WEDNESDAY

Fleetwood Mac

Some (ahem) thought the band’s December performance at Philips Arena was the top concert of 2014. If you missed it, this is another chance to see just how strongly the return of Christine McVie elevates the game of bandmates Lindsey Buckingham, Stevie Nicks, John McVie and Mick Fleetwood. If you’re returning for an encore viewing, well, you already know the potential for magic being conjured onstage.

8 p.m. March 25. $49.50-$179.50. Philips Arena, 1 Philips Drive, Atlanta. 1-800-745-3000, ticketmaster.com.

THURSDAY

Incognito with Maysa

The funk-jazz-soul band — pioneers of the “acid jazz” movement — is launching its 2015 tour with this Atlanta date. The band has earned hits with covers of Stevie Wonder’s “Don’t You Worry ’Bout a Thing” and Ronnie Laws’ “Always There.” Singer Maysa has been with Incognito since the early ’90s but has maintained an active solo career as well. Her ninth album, “Motions of Love,” in 2011, debuted at No. 1 on the Billboard contemporary jazz chart. In 2013, she released “Blue Velvet Soul.”

With Khari Cabral Simmons and Chantae Cann. 8 p.m. March 26. $29-$89. Cobb Energy Performing Arts Centre, 2800 Cobb Galleria Parkway, Atlanta. 1-800-745-3000, ticketmaster.com.
