But it was another local rapper whom SIN has paid homage to as an inspiration since high school and refers to as a big brother, Chief Tone.
"I can call Chief and Chief will come in a heartbeat, no matter where he is," SIN said. "It's definitely about loyalty and respect with me and him."
So after Chief Tone declared his retirement from rap last year, SIN took it upon himself to take action to make sure that wouldn't happen.
"When Chief actually went on Twitter and he was like, 'Oh, I'm going to call it quits,'" SIN remembered, "I really had to call him, went to the studio, he came to the studio where I was at, had an emotional talk with him there, and now Chief is working on a new project. I can't let him stop rapping, because that was my fuel. He kept me going. I just can't let him stop, because things aren't working out for him."
Accompanied by his northeastern tone and style, SIN's latest release, A Toast To You, is a 12-track project complete with lessons on rapper's misguiding their listeners and stories of the women he lays with at the end of the night. On the album, he is assisted by QuESt as the lone feature.
Maybe the biggest sign that the rapper is continuing to push forward personally is the lack of mention of Clayton's name in this project.
"Through time, I realized that he was going to be with me regardless of wherever I go," said SIN. "But if I do happen to catch a glimpse of him and his family there, I know that it's just him subconsciously."
Since Clayton's death, two men, Jamal Smith and Quinton Lythgoe, have been arrested and charged with first-degree murder with a firearm and robbery with a firearm.
And even though Clayton is unable to be at SIN's every show anymore, it does not mean he is not around.
"I'll have a dream where I see him break in a room in a room like, 'Yo, what up?'" said SIN. "You know, sit down next to him like, 'What up, man?' Everything's cool. But, they're dreams. You know what I'm saying? So, it is what it is."
