The doors are still open

What may just be the single greatest rock band to ever come out of Escatawpa, Miss., 3 Doors Down, has been rocking bros the world over since the release of its hard-charging modern rock smash "Kryptonite" in 2000. With some 15 million in album sales on the strength of parking-lot power ballads like "Here Without You" and "When I'm Gone," the band has kept the success rolling this year with its No. 1 self-titled album. Tracks like the earnest "It's Not My Time" and the support-the-troops rock of "Citizen Soldier" find the band in top form. 3 Doors Down performs tonight with brothers in stadium rock balladry Staind and Hinder. 6:30 p.m. $18-$68. Comcast Center, 885 South Main St., Mansfield. 617-931-2000. ticketmaster.com
