I love bluegrass and Celtic fiddle. Alison Kraus and Union Station, Natalie MacMaster are right up my ally.
I play a bit of country fiddle (poorly), and gathering around a campfire with a couple of banjo players, quitar players, someone on a "stump fiddle", someone with some spoons or bones, someone passing a jug... man, that's some good times!
I enjoy some Classical, as long as it's strong on the string aspect. Poet and the Peasant is a favorite, as is Pachelbel's Canon.
I also like some classic rock- Jethro Tull, Tom Petty, Led Zeppelin, Pink Floyd, Heart, Fleetwood Mac, ZZ Top, Lynard Skinnard, etc.
Johnny Cash, Willie Nelson are on my MP player...
I'm a big John Denver fan, believe it or not, hehe!
I generally listen to country radio stations, but swap for CD's since they rarely play my favorites...
People love to ride places with me and listen to my CD's, lol! NOT!
