Ghostface Killah's latest album is called "Sour Soul" and it's a collaboration with some Canadian guys called BADBADNOTGOOD. You can't buy it yet but you can stream it. I suggest you go get your headphones and start listening. For the third album in a row Pretty Tone chose to work with a live band instead of rhyming over samples or computer-produced sounds. All three have a vintage soul vibe but these particular tracks have a 70's funk feel reminiscent of the movies I used to watch on Sunday afternoons on WWOR and WPIX when I was a kid.
That probably provides no context for you, but suffice it to say that there's something authentically vintage about this music. I don't think this will go down as one of GFK's all time classic albums, but it's definitely an interesting continuation of an already interesting departure from his previous style.
My favorites are Ray Gun, Nuggets of Wisdom, Mind Playing Tricks, Food and Gunshowers.
