This 13-track CD, which comes with access to 7 additional tracks which can be downloaded, seems to have been on the street since November 17, 2017. I just ordered it, so I can't comment on the content, but I don't recall having seen any announcement - here, or in any of the other places I normally check.

Description
2017 release including digital download for featuring additional new recordings. Coming off her critically acclaimed, Polaris prize winning 2015 album Power in the Blood, and after winning the 2016 spirit of Americana Award, Buffy Sainte-Marie has delivered Medicine Songs - and has made it her mission to educate and inform the world using her strongest tool - her music, by - in her own words - "putting the songs to work". The album starts with the new unreleased collaboration with fellow Polaris prize winning indigenous artist Tanya Tagaq, followed by the politically charged "The War Racket." There are also new recordings of some of the most powerful songs Buffy's ever written, including "Bury My Heart at Wounded Knee," "Starwalker," timeless protest classics like "Universal Soldier," "Now That the Buffalo's Gone," and "Little Wheel Spin and Spin," as well as forgotten gems that were simply ahead of their time when first released, like the shimmery, eye-opening "Priests of the Golden Bull," and the chillingly prescient "Disinformation."
