Artist: Jay Z

Gimel “Young Guru” Keaton is one of the most famous studio engineers in music history, primarily because Jay Z has shouted him out often on tracks like “My 1st Song” and Young Jeezy’s “Put On (Remix).” Keaton linked up with Jigga early in the rapper’s career and wound up being a constant presence at Baseline Studios during the heyday of Roc-A-Fella Records. And even as many of Jay Z’s partners in music and business have come and gone, Young Guru has remained in the fold, expanding his role into label business and even DJing for the Watch the Throne tour.
