45 King, who has produced for Jay Z & Eminem, among others, says he had a heart attack.
"Had a heart attack...Wednesday [January 22]," 45 King said in his Twitter statement. "My blood needs more oxygen. It's a hard knock life...Wish me luck!"
45 King's reference to "Hard Knock Life" recalls the beat he produced for the Jay Z selection of the same name.
"He goes in an out of the scene," Jay Z said of 45 King in an excerpt from a film on King's YouTube page. "He came back and he made 'Stan' for Eminem. He does these great and remarkable cultural things that grab culture. He's actually a genius in that way. And then he just disappears for years."
