Allan, one of mainstream country’s most thoughtful craftsmen, released his latest album, “Get Off on the Pain,” in spring 2010. The album’s promotional push was interrupted when Brooks & Dunn’s “Last Rodeo” tour, which Allan was opening, was postponed due to Ronnie Dunn’s doctor-mandated vocal rest. That incident prompted Allan to seek medical attention for his own vocal issues, and now he’s back on the road after having a polyp removed from his vocal cords in late 2010.

The Last Waltz Ensemble Presents Blue Waltz for Sean Costello Memorial Fund
Atlanta guitarist, singer and songwriter Costello died one day shy of his 29th birthday in 2008. His mother, Debbie Costello Smith, has established an organization in his honor, the Sean Costello Memorial Fund for Bipolar Research. The Last Waltz Ensemble is a group of local musicians who play the music of Bob Dylan and the Band, often bringing in guest musicians. One of those musicians was Sean Costello, who played one of his last gigs with the group. The ensemble has gathered an impressive list of those guest musicians, including many who worked with Costello, for this tribute to the late guitarist. The show also serves as a fundraiser for the organization named for him.
8 p.m. Aug. 19-20. $25; $20 in advance. Smith’s Olde Bar, 1578 Piedmont Road N.E., Atlanta. 404-875-1522.
My Morning Jacket, Neko Case
Kentucky quintet My Morning Jacket has been building an audience for more than a decade now. The band’s sound has evolved over the years, too, demonstrating an unwillingness to remain in one place for very long. The reverb-drenched haze of the early years has given way to pop adventuring and an exploration of the vast array of influences — from Prince to Neil Young — that course through the band’s work. Case is one of the finest singers in popular music. The Virginia-born chanteuse’s forceful yet tender voice seems as comfortable deep in a country song as it does wailing amid crunchy rock guitars. Her latest album, “Middle Cyclone,” was among 2009’s most critically lauded, landing at No. 3 on the Village Voice’s annual year-end critics’ poll.
7:30 p.m. Aug. 20. $34-$46. Verizon Wireless Amphitheatre, 2200 Encore Parkway, Alpharetta. 404-733-5010.
Melding reggae and orthodox Judaism might seem odd, but it doesn’t sound that way. Matisyahu’s music is no kitschy gimmick. His solid take on reggae blends hip-hop influences, memorable songs, superb playing and Matisyahu’s keening voice. He’s amassed a catalog of three studio albums since his 2004 debut, and even scored a Top 40 hit in 2005 with “King Without a Crown.”
8 p.m. Aug. 22. $26; $24 in advance. Center Stage, 1374 W. Peachtree St. N.W., Atlanta. 404-885-1365.

8 p.m. Aug. 22. $23; $20 in advance. Vinyl, 1374 W. Peachtree St. N.W., Atlanta. 404-885-1365.
Richard Buckner, David Kilgour
Buckner’s remarkable discography includes a song cycle based on Edgar Lee Masters’ “Spoon River Anthology” (the intimate beauty “The Hill”) and a sparse, heartbreaking chronicle of divorce (“Impasse”). It was a long five years between 2006’s “Meadow” and the just-released “Our Blood,” a period troubled by tape-machine death, a burgled laptop and a score for a film that never materialized. Kilgour founded one of the more influential obscurities of the ’80s, the Clean. The droning, lo-fi pop of the New Zealand band (and of fellow travelers on the beloved Flying Nun record label) made a noticeable impact on a few influential bands that followed, including Yo La Tengo and Pavement. His solo career began in 1991, running concurrently with the occasional reformation of the Clean.
7 p.m. Aug. 23. $16; $13 in advance. Smith’s Olde Bar, 1578 Piedmont Road N.E., Atlanta. 404-875-1522.

Guster, Jack’s Mannequin
Guster is a quirky pop combo from Massachusetts with an acoustic bent and a college-band sensibility. The band has built a large and loyal following through seemingly endless touring and a charismatic live presence. This gig marks the band’s second Atlanta appearance this year, following a Tabernacle show in February. When California pop-punk outfit Something Corporate took a hiatus, piano-playing frontman Andrew McMahon formed Jack’s Mannequin. Following a reunion tour with his Something Corporate bandmates last year, McMahon is back with Jack’s Mannequin and the band will release its third album, “People and Things,” in October.
7:30 p.m. Aug. 24. $26-$36. Chastain Park Amphitheatre, 4469 Stella Drive, Atlanta. 404-733-4949.
