It's been a hell of a promotional week for Jay Z. Magna Carta Holy Grail didn't come out to such rave reviews; the ridiculous method of distribution to being with or overhype aside. In our review, we discussed Jay's intent to merely be a commercial success rather than a critical one; hence his method of distribution via Samsung guaranteeing the album Platinum status before it was even released. This weekend's Wireless festival in Stratford, then, could be seen more as yet another promotional tool used by Jay, performing, not once, but twice as a headline slot. As well as this, starting tonight, Jay Z will be in conversation with BBC Radio 1's Zane Lowe.

According to NME, in this interview Jay states that he had already begun work on 'Holy Grail' and 'Oceans' (the former featuring Justin Timberlake and the latter, Frank Ocean) while he and Kanye West were working on their collaboration Watch The Throne. Jay and Kanye had agreed that they would start work on their respective solo albums after the release of WTT but it appears Jay gave himself a head start.

After playing the two tracks (at this point without the Timberlake or Ocean guest vocals), West reportedly demanded the tracks were put on WTT rather than MCHG: "[There were] no lyrics on 'Holy Grail' and I recorded 'Oceans' and I played those records for Kanye. And he was like, 'No those have to go on Watch the Throne,' so we spent four days arguing about those records and I was explaining to him why it wasn't right for this project and I had a whole idea for making this album called Magna Carta... Holy Grail [part of] the name came after."

Though they did argue, Jay made it clear that it didn't end up in actual fighting instead mainly being "four days literally arguing" with a bit of "pushing at one point but not between us, just everyone else got a little excited."
