Critic’s picks: Pop music


BRUNO MARS  He’s known as a smooth operator, but Mars shook loose from that image a bit on last year’s “Unorthodox Jukebox,” which added some Prince-style raunch to his silky R&B. Touring behind their new sophomore album, “More Than Just a Dream,” retro-soul revivalists Fitz and the Tantrums will open the show before their own headlining (and sold-out) gig at the Paradise two nights later. June 26, 7:30 p.m. Tickets: $37.50-$91.50. TD Garden. 800-745-3000,

JUANES  Long established as one of Latin America’s most prominent rock musicians, whose songwriting concerns range from social justice to matters of the heart, this Colombian superstar comes to town for a rare club date in support of 2010’s “P.A.R.C.E.”  June 23, 7 p.m. Tickets: $49.50-$79.50. House of Blues. 800-745-3000,

JOAN BAEZ  As part of the Lowell Summer Music Series, the folk matriarch returns home to the part of the country that launched her more than five decades ago. Recent performances suggest Baez is especially nimble, in voice and on guitar, as she delves into her long and storied career. June 28, 7:30 p.m. Tickets: $55, $47 in advance. Boarding House Park, Lowell.
