This piece is old at this point, but don't think it has been shared here? Jneiro Jarel giving short descriptions of the JJ DOOM album and Bookhead EP, working with DOOM: https://daily.bandcamp.com/2017/06/14/jneiro-jarel-guide
"DOOM and I were in Beverly Hills and used to live in a compound; I had my section, he had his section. But when it came to recording, me and him would sit up for hours and hours talking about music, like ’90s hip-hop, all the Portishead stuff and all the Radiohead connections, ’cause he didn’t know anything about those artists; he didn’t know who Thom Yorke was, he didn’t know who Beth Gibbons was, he didn’t know who Massive Attack was, and I came from a lot of that. So we had these meetings where I schooled him on other types of music that I felt me and him should get involved with.
So all that stuff you hear [on Keys To The Kuffs] with him being open to that; it had a lot to do with educating him on those artists. When we started recording, he had to understand it. But DOOM couldn’t care less, man! [Laughs] People do not understand. He could not care less. But that’s how he works, and you’ve got to respect it. We know DOOM as a villain—a very kind one—but he’s a villain, man."
"The Bookhead EP is awesome and I’m glad people were down to remix it. I think it stands the test of time. But with DOOM, man, you’ve got to juice it ’cause it’s hard to get him to do more music!
Working with DOOM is like… Well, you can’t get in the studio and think what you’d typically expect when you work with someone. Normally you’d say, ‘Let’s get in the studio, I’m free from this time to that time, I got a song I’d like to show to you and let’s see what we can do.’ Then they show up, they do it, and it’s much love until the next time.
But with DOOM, you can say whatever time you want. He’ll say, ‘Word, word, word,’ but that doesn’t mean he’ll be there. So I had to learn how to juggle around that way of working with him. DOOM’s definitely on his own time, and on a clock that no one else has. Once I learned that, everything was fine. DOOM’s different, he’s unorthodox, he’s an alien."
