"Country", or "Country & Western" appears to be the one genre that people are least likely to admit to liking, and when they do, it is often followed by a disclaimer or qualification.
Whilst my genres of preference are mainly Blues/Rock/Folk (my own personal disclaimer) I must admit to having a soft spot for some Country music, and "Country Rock" in particular. In fact, the very first record I ever owned (at the age of around 5, and bought for me by my older sister) was a single called "End of the World" by Skeeter Davis. My liking for Country Rock and bands such as "The Flying Burrito Brothers" and Gram Parsons in particular was reinforced by seeing Emmylou Harris in concert a couple of times in the mid 70s with her amazing band (James Burton on lead guitar first time round, and Albert Lee the second time). Believe it or not, her popularity in the UK was largely down to the fact that John Peel used to play her first two albums regularly on his show, and would comment on the "fine figure of a woman" on the "Elite Hotel". He wasn't wrong. I think every male in the mid 70s in his late teens or early twenties was completely besotted by Emmylou. Still a 'fine figure of a woman to this day!
Emmylou Harris would certainly be my 'Queen of Country', joined by two of the finest female vocalists (in my opinion), in Patsy Cline and Alison Krauss. I do like some Lucinda Williams albums as well.
On a related (to country music in general) note, in my opinion Hank Williams has to go down as one of the very best songwriters (of any genre), and up there with the likes of Dylan & Cohen.
