Heard he passed peacefully in his sleep. Cause is unknown.
PUTS was one of my favorite groups. I personally think that they have the best catalogue of any hip-hop group in the 21st century. And Double K was great in the group. Brought a great mixture of coolness, humor, and story-telling ability. And the time I met him he was extremely cool.
They also had a helluva live show. Saw them probably 5 times, and loved it every time.
