Jonathan Abrams: Halo-Pac is kind of eerie to me. I am someone who wanted to believe Tupac still lived for so long, record after record, until I finally gave up hope somewhere around 2001. Tupac Shakur is my John F. Kennedy assassination and moon landing. I hit adolescence and grew up in California. It was Pac and I thought he would get back up and make a record about it. I’ll never forget where I was — at a friend’s house when I learned of his death.
