While in prison, Tupac Shakur studied the works of Makaveli, and used it as an alias for The Don Killuminati, which amounts to little more than a call to war. The 7 Day Theory, released less than two months after his death, is a slightly grisly listen. From the distinctly uneasy experience of 2Pac cussing Notorious B.I.G, Jay-Z and Nas on the intro, you are then faced with the prospect of listening to a very macabre album. The DVD Side of the Dual Disc edition includes never-before-released footage and more. Koch. 2005.
