That's tragic and sad news to hear. I liked some of the Dixie Chicks stuff, never saw them live tho. Back in the 90's I was Bar Mgr at place where we did live music 4-5 nights/week. The GM that did the bookings gave me a stack of demos to listen to, we'd get tons of demos and one of them was from the original Dixie Chicks lineup. We did a lot of regional acts, all kinds of genres but mostly Americana, type stuff, Robert Earl Keen, Joe Ely, etc., so thought they would fit in. The GM told me that Lloyd Maines' daughter, Natalie, had just joined the group and they were getting a lot of buzz and might be too late to get them. Sure enough, started seeing their names everywhere and they blew up shortly after that.
