Dierks Bentley will perform an acoustic tribute to Brooks & Dunn when they're presented the Country Radio Broadcasters' Career Achievement Award during the 2010 Country Music DJ and Radio Hall of Fame induction ceremony. The event takes place Feb. 23 at the Nashville Convention Center. Brooks & Dunn plan to retire after their Last Rodeo tour ends in August. Bentley opened the duo's Australian tour in 2009. "When we toured together, I watched their show every night from sidestage in total awe of the number of hits they've had and what they've built over the last few decades," Bentley said. "They've done it all. I still can't believe they're about to retire."
