It's funny you should post that right now EL. I was just doing a search and reading up on them to find out what's been done lately and according to Wiki, not a whole lot since 2008. And I quote....
"] [edit] Recent projects
A proposed April 2008 commercial spot to promote Al Gore's "We Campaign" involving both the Dixie Chicks and Toby Keith was eventually abandoned because of scheduling conflicts.
While the Dixie Chicks have been uniquely successful, other up-and-coming all-female bands that have been compared to them include the Canadian band Po' Girl, the Australian trio The McClymonts, and the American trio The Shells.
Martie Maguire and Emily Robison will be releasing new music in 2010 without lead vocalist Natalie Maines. Lloyd Maines, Natalie's father, has stated that the trio are "definitely still an entity".On January 15, it was announced that duo will be known as Court Yard Hounds and will release an album in May with Robison on lead vocals.
On March 16, 2010, the Dixie Chicks announced they will be touring with music group The Eagles. The tour begins on June 8, 2010 in Toronto, and has eight shows announced concert dates so far. The tour will be stadium-based, visiting cities such as Boston, Chicago, Philadelphia, Washington, St. Louis and Winnipeg. Country singer Keith Urban will appear at selected concerts."
Sounds like 2 of them have plans to release new music but other than the big announcement the other day, notta!!!
IMO, DC's might benefit from touring with the Eagles (and I fear that is exactly why they are doing this) but again I ask, WHY are the Eagles doing this? I will repeat (and have already) again and again---it just doesn't make much sense to me. After filling venue after venue the last couple of years, why include anyone else on the bill?
