Kennedy & Tremonti perform three Alter Bridge songs, discuss latest album "Fortress," and more.

Alter Bridge singer/guitarist Myles Kennedy and guitarist Mark Tremonti  visited Billboard's studio to discuss the making of the band's latest album, "Fortress," and how the band's sound has evolved during the past decade.

The pair also gave an exclusive acoustic performance of "Addicted to Pain" and "Rise Today" (from second album "Blackbird"). By special request, Kennedy also performed "Watch Over You," another "Blackbird" single that became an unofficial anthem to the second season of "Celebrity Rehab."

It's been 10 years since Alter Bridge made its debut with the album "One Day Remains." The foursome has forged a path to touring, sales and chart success at a not-quite-slow but definitely steady pace, and that route is paying off yet again with "Addicted to Pain," the lead single from 2013's "Fortress." Though it was released last August, the track has been climbing Billboard's Rock Airplay chart, moving from No. 29 to No. 22 this week.

Watch the videos above to see what Kennedy and Tremonti have to say about the musical journey that Alter Bridge has experienced thus far.
