Original songs, original lyrics, stories to be told and heard. It's always best to hear the storyteller express his/her own thoughts and tales in their own unique voice and style. I've been so heavily into jazz the last three or four years that I've largely gotten away from the storytellers.
It always feels like a genre of the 1970's but there's still plenty of these voices around.
The highlight for me though, is a cover version of the Mark Knopfler/Dire Straits song, 'Brothers In Arms.' Backed by an organ and mandolin, it's absolutely beautiful and had me lifting the tonearm and moving it back to listen again, multiple times.
