Acclaimed country music duo Brooks & Dunn have decided to part ways. Fans will have plenty of time to get used to the idea, as the two have concert dates scheduled through the fall, a “#1′s and Then Some” album scheduled for release September 8, and a farewell tour, “The Last Rodeo”, planned for 2010.

The pair posted a letter to fans on their website:

To Our Fans:

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…. We owe it all to you, the fans. If you hear rumors, don’t believe them, it’s just time.

We will release our #1′s and then some” on September 8th and bid you farewell one last time in 2010, with The Last Rodeo Tour…(dates to be announced).
