This man was mentioned to me a while ago, I remember looking up and enjoying his work. Now I have forgotten his name but I will say what I remember.
He was formerly a musician, around genres jazz or rock
He was black
Most of his paintings were of cityscapes, very highly detailed but with little realism, bold colours were used allot, and perspectives often were squired.
If found we can discuss him, thus not an /r/ thread, they wouldn't know anyway.
Pic is closest to his kinda of work I could find, still not too similar.
