Jay-Z
According to his mother, Jay-Z used to wake up his siblings at night banging out drum patterns on the kitchen table. She bought him a boombox for his birthday, sparking his interest in music, and he began freestyling and writing lyrics. Known as "Jazzy" around the neighborhood, he later adopted the stage name "Jay-Z" in homage to his mentor Jaz-O. Jay-Z can be briefly heard on several of Jaz-O's early recordings in the late 1980s and early 1990s, including "H. P. Gets Busy", "The Originators" and "Hawaiian Sophie". Jay-Z became embroiled in several battles with rapper LL Cool J in the early 1990s. He first became known to a wide audience on the posse cut "Show and Prove" on the 1994 Big Daddy Kane album Daddy's Home. Jay-Z has been referred to as Big Daddy Kane's hype man during this period, although Kane explains that he did not fill the traditional hype man role, and was instead basically making cameo appearances on stage. "When I would leave the stage to go change outfits, I would bring out Jay-Z and Positive K and let them freestyle until I came back to the stage." The young Jay-Z appeared on a popular song by Big L, "Da Graveyard", and on Mic Geronimo's "Time to Build", which also featured early appearances by DMX and Ja Rule in 1995. His first official rap single was called "In My Lifetime", for which he released a music video in 1995. An unreleased music video was also produced for the B-side "I Can't Get with That."
