Before the days of Montgomery Gentry or Big and Rich, there were Brooks and Dunn, popwise neohillbillies keeping the cause of the good ol' nice guy alive in the Age of Shania. The pair have said they're retiring, but this best-of proves the almost metronomic consistency of their rolling, revved-up honky-tonk. They liked girls who looked like Madonna but listened to Merle, and their rock-friendly formula was so Purple American that Bush and Obama both pumped the big-dreaming "Only in America" at their party conventions — inspiring many, annoying few and offending no one.
