yes I know! they recorded the Nashville show, that should so be released some how for fans.
I'm not sure about a new album. I do know that the first year of motherhood is very hard and tiring. I'm not sure she would have the energy to really write or play around with songs. She may have jotted things down or has ideas in her head. now that she's past the first 18 months things should be looking up for her in regards to the child/seeping/routines/etc. she may have more time to explore things she may have felt/thought during that first year. I Hope that some of her new material, if she has any, will have a little to do with her growing family.
2018 seems a hefty goal for our girl, lol. I mean, liberman was in the works for a loooooong time before it actually came out. rabbits too! I think 2018 is very optimistic.
