J. COLE Built slowly on the back of mixtapes, his rise was not immediate. But once J. Cole found his footing on his debut, 2011’s “Cole World: The Sideline Story,” he promptly rose to the ranks of arena-ready hip-hop. For this tour, Cole has fellow rapper Wale with him. Sept. 24, 7:30 p.m. Tickets: $37.50-$57.50. Agganis Arena. 800-745-3000, www.ticketmaster.com
AUSTRA A classically trained opera singer, frontwoman Katie Stelmanis’s full-throated vocals add a chilling tension to this electro-pop band from Montreal. Following up 2011’s acclaimed “Feel It Break,” Austra recently released “Olympia,” whose dark-hearted songs throb and rumble with influences from house music and tropical percussion. Sept. 24, 8 p.m.
Tickets: $15. 800-745-3000, www.ticketmaster.com
MICHAEL BUBLÉ Already on the road after the August arrival of his newborn son, this irrepressible Canadian singer exudes an effortless charm on songs both old and new.

TD Garden. 800-745-3000, www.ticketmaster.com
