Have a feeling Mark has been busy producing and recording for another artist recently. (Ruth Moody? Much silence on her FB page and website)
Probably did also some of the usual pre-recording too with GF, this autumn, for his next album . MK's band will probably get together in the studio early 2017 for a few weeks of recording sessions and album will be released around September. Mixing en mastering around may. Art work, pressing CDs/Vinyl, distribution etc. during the summer.
Neither wouldn't it suprise me that he is working on somekind of duet album again, featuring Emmylou, Ruth, Evelyn Glennie and others.
Personally I wouldn't mind a more guitar based album with roots of the American Heartland (OES, STP), feat. artists such as Derek Trucks, Joe Bonamassa, Jerry Douglas, Bela Fleck, Sonny Landreth... but that is wishful thinking
