Shelby Lynne's two albums (the new one and "I am Shelby Lynne) are definitely good one's IMHO. If anyone wants some others to check out in the genre, my recommendations are:
Bettye LaVette (real soul)- Scene of the crime
Buddy and Julie Miller- same
Jollie Holland- Escondida (more New Orleans jazz I guess)
Tift Merrett- Bramble Rose
Laretta Lynn- Van Lear Rose
Another really good LP I just got was Rickie Lee Jones- It's like this.... The 45rpm Analog prod. deal..... Really, really good stuff
