There will always be some promo. Not that he is doing that much for his last albums. Correct me if i am wrong but i see other artist doing much much more promo things when they have a new album..
Privateering and Tracker didn't had what we call showcases, small concerts, just some radio interviews and short tv interviews sometimes playing one song, probably because Privateering release was pretty close to the Dylan tour in 2012 and Tracker was released also close to the MK Privatracking tour, so there was not enough time to do some showcases.
As far as we know, from the new album release this autumm, there is nothing in MK schedule until April 2019 with the musical premiere, but it's supposed until then MK would keep working in the musical so, who knows if this time he would have time for some showcases...
I hope so!
