I listen to Witt Lowry because his raps are stories and he has a nice slow, calm flow. I also will listen to K.A.A.N who is a faster, upbeat rapper to get lost in his lyricism, alliteration and flow.
They aren't very well known and I'm willing to bet nobody on this site has heard them but if you have are open minded when it comes to music, I'd give them a listen. Warning, K.A.A.N is explicit and not for everyone. Witt Lowry rarely swears.
Kindest Regards or Dreaming With Our Eyes Open by Witt Lowry are two that are very calming and tell a story.
Kaancepts by K.A.A.N is a very fast rap that you can get lost in and listen to the flow.
Phoenix, Concealed the Outro, and White Lines are a few from K.A.A.N that tell some of his personal story.
