September 13 was the nineteenth anniversary of Tupac Shakur’s death.

To honour the occasion, Kendrick Lamar has posted a poignant tribute on the late rapper’s website. The official 2Pac Facebook page confirmed the letter was from Lamar.

“I was 8 yrs old when I first saw you. I couldn’t describe how I felt at that moment. So many different emotions. Full of excitement. Full of joy and eagerness,” Lamar writes. “20 yrs later I understand exactly what that feeling was. INSPIRED. The people that you touched on that small intersection changed lives forever. I told myself I wanted to be a voice for man one day. Whoever knew I was speaking out loud for u to listen. Thank you.”

Lamar featured a fictional posthumous conversation with Shakur on his most recent album, which he almost titled Tu.P.A.C.
