It's truly heartbreaking to witness such a great talent - who I feel can carry the Bay Area back to relevance in the rap game - struggle with real life issues that hinder musical progress. Pray for Stickpen the Kingpen...
Sorry to hear and hopefully you don't take this as a value judgment regarding the artist but cats need to learn how to separate their street lives from music business lives as when the two intersect it is never a good look and the commercializing of any person's troubles doesn't make it easy.
And when you sign a contract with an artist, and they get out on the same day you post this comment. You shouldn't ignore there calls and emails. People make mistakes. Now who's in breach of contract? You or your artist?
