One day, while working on Blueprint 3 at Baseline Studios, Jay-Z wanted a scratch hook for one of his tracks. Two people in the studio – Just Blaze, who he knew could DJ, and Young Guru, who he ‘heard’ could DJ. What began as a friendly DJ competition between the legendary producer and world-renowned engineer, soon lead to Young Guru becoming Jay-Z’s tour DJ. In preparation for their upcoming tour, Guru and Just discuss their work on Roc-A-Fella Records' most classic albums and their friendly competition.
