Country duo Brooks & Dunn are done - Ronnie Dunn has quit the group to go solo. Dunn formed the act with Kix Brooks in the late 1980s and made their debut in 1991.

They quickly became one of the most acclaimed country combos of all time - their first album, "Brand New Man," was certified six-times platinum and all four singles from the release hit the top of the country charts. Twenty of the 40-plus singles they've released have hit the top of the charts. The duo has recorded 10 studio albums.

Brooks & Dunn have won 19 CMA Awards, including 14 in the Vocal Duo or Group category, and 24 ACM Awards, including 15 as the Top Vocal Duo. They also won two Grammys for Best Country Performance by a Duo or Group.

To date, they've sold more than 30 million albums.

A statement from Brooks & Dunn reads, "After 20 years of making music and riding this trail together, we have agreed as a duo that it's time to call it a day. This ride has been everything and more than we could ever have dreamed. If you hear rumors, don't believe them. It's just time."

The duo will release a new greatest hits compilation in September, and Brooks & Dunn will tour "one more time" in 2010 before calling it quits.
