I have found it really hard to get any information on this forthcoming release. Her web site has nothing and I eventually found a wee bit of info on the Rounder website:
"The Age of Miracles is Mary Chapin Carpenter’s third release on Zoe/Rounder Records. Written and recorded over the past three years, The Age of Miracles is a personal exploration of regret and resilience from the world-renowned singer-songwriter as a well as larger, more universal expression of wonder at the times we are living in. The record features an incredible line-up of musicians, including longtime collaborator Matt Rollings (piano, B-3 organ) as well as Russ Kunkel (drums), Duke Levine (electric and acoustic guitar) and Glenn Worf (bass). Also featured on the album are guest vocals from Vince Gill and Alison Krauss. "
Released on 10 May 2010 according to Amazon and from the previews another solid album from MCC!
