Brooks & Dunn were fairly early into their career when they began shattering records. The duo released their debut album, Brand New Man, in 1991, and by 1994 they entered the history books as the first country music duo to ever have an album certified quadruple platinum when it marked four million in sales.

Both men had kicked around the music business in Nashville for several years before they joined together somewhat reluctantly at the behest of Tim Dubois at Arista Records. They joined up with songwriter Don Cook and producer Scott Hendricks to produce their debut album and teamed with Cook to write the title song, which they released as their first single on June 10, 1991.

"Brand New Man" gave Brooks & Dunn their first No. 1 hit less than three months later, and they scored three more No. 1 hits in rapid succession with "My Next Broken Heart," "Neon Moon" and "Boot Scootin' Boogie," while a fifth single from the album, "Lost and Found," reached No. 6.

'90s Country Acts That Need to Return!

Kix Brooks and Ronnie Dunn released their follow-up album, Hard Workin' Man, in 1993 and scored another handful of hits, including two more chart-toppers with "She Used to Be Mine" and "That Ain't No Way to Go," and they had released their third album, Waitin' on Sundown, by the time the RIAA certified Brand New Man for four million in sales on Nov. 29, 1994. Hard Workin' Man was certified triple platinum that same day for sales of three million, but that was just the beginning for the superstar duo, who went on to become the top-selling country duo of all time and one of the most awarded acts in county music. Their unbroken string of hits lasted all the way until 2009, when Brooks & Dunn announced they were going their separate ways.

The duo performed what was billed as the final show of their career in Nashville in 2010, but that wasn't the end of the road for the history-making team. Brooks & Dunn reunited in 2015 for a Las Vegas residency with Reba McEntire billed as Reba, Brooks & Dunn: Together in Vegas, which has been so successful that it's been extended into 2018.
