FRIDAY

Music Midtown

A quartet of headliners — Eminem, Jack White, John Mayer and Zac Brown Band — anchor the 2014 edition of the Atlanta festival, which will commandeer Piedmont Park for two days. A couple of changes this year: Only two-day passes are available, and each night will boast two headliners among the three stages. Old-school rap fans can break out the Adidas for Run-D.M.C., but other acts will bring down the average age of the bill, including Iggy Azalea, Lorde, Lana Del Rey, Bastille, Fitz and the Tantrums, B.o.B. and Twenty One Pilots.

Gates open at 4 p.m. Sept 19 and noon Sept. 20. $135 two-day pass (VIP options available for $500-$1,000). Piedmont Park, Atlanta. 1-800-745-3000, ticketmaster.com.

Keb’ Mo’ and Mavis Staples

Strap yourselves in for this doubleheader of blues and gospel. Keb’ Mo’ recently released his 12th studio album, “BluesAmericana,” a collection of 10 tracks that blend his honest lyrics with his bluesy roots-rock guitar. Despite artists as varied as the Dixie Chicks and Tom Jones recording his work and his own collaborations with everyone from Bonnie Raitt to Amy Grant, Keb’ remains a fairly under-the-radar marvel. Gospel great Staples, 75, last year released her 14th studio album, “One True Vine,” produced by Wilco’s Jeff Tweedy.

8 p.m. Sept. 19. $51.50 ($49.50 for members). Atlanta Botanical Garden, 1345 Piedmont Ave. N.E., Atlanta. 1-877-725-8849, ticketalternative.com.

SATURDAY

Susan Werner

If you want an example of Werner's brilliance with a theatrical score, check out "Bull Durham," the musical version of the cherished film now playing at the Alliance Theatre. Werner, a Midwestern native, whacks a home run as composer of the show as she deftly melds influences from Southern rock to gospel to soul. In a recent interview with The Atlanta Journal-Constitution, Werner mentioned that, at her Eddie's Attic return, she might play some of the cuts that didn't make it into the rollicking "BD." Expect to hear plenty from the rest of her 20-plus-year career as well.

7 p.m. Sept. 20. $25 (advance general admission); $50 (advance VIP, includes sound check and autographed CD); $32 (general admission at the door); $125 (reserved table of four). Eddie’s Attic, 515-B N. McDonough St., Decatur. 1-877-725-8849, ticketalternative.com.

TUESDAY

Carbon Leaf

It’s hard to believe that this Richmond quintet has been rolling out their refreshingly original Celtic-tinged indie folk-rock for more than two decades. Through the years, the band has escalated from playing college frat parties to becoming the first unsigned band to perform on the American Music Awards after their song “The Boxer” won a nationwide contest. Carbon Leaf recently rereleased its 2004 album, “Indian Summer,” as “Indian Summer Revisited,” featuring rerecorded versions of the album’s songs, including the Triple-A radio hit “Life Less Ordinary.”

With Caroline Glaser. 8 p.m. Sept. 23. $15 (advance), $18 (day of show). Vinyl at Center Stage, 1374 W. Peachtree St., Atlanta. 1-800-745-3000, ticketmaster.com.

WEDNESDAY

Experience Hendrix

This all-star celebration of Jimi Hendrix’s music launched in 1995 as a tribute concert at Seattle’s Bumbershoot Arts & Music Festival. Since the early 2000s, it’s alternated between a one-city tribute show and a full-fledged tour with a rotating cast of guitar luminaries. This year’s fall run kicks off Friday in Fort Lauderdale, Fla., and will spotlight Kenny Wayne Shepherd, Buddy Guy, Jonny Lang, Zakk Wylde, Rich Robinson, Eric Johnson and others, along with bassist Billy Cox anchoring the groove.

8 p.m. Sept. 24. $55-$65. Cobb Energy Performing Arts Centre, 2800 Cobb Galleria Parkway, Atlanta. 1-800-745-3000, ticketmaster.com.
