Curtis Fisher (born 18 April 1961), better known by his stage name Grandmaster Caz, is an American rapper and DJ. Caz first encountered hip hop in 1974 at a Kool DJ Herc outdoor party. He soon bought his own equipment and teamed up with JDL to form the duo, Notorious Two, around 1977. During this period, he became the first person to perform both DJ and MC duties. He and JDL later joined The Cold Crush Brothers in 1979.
In 1979, Sylvia Robinson, label head of Sugar Hill Records, overheard Caz's friend Big Bank Hank rapping over one of Caz's practice tapes. Impressed by Hank, she invited him to join the group The Sugarhill Gang, who were set to record the first rap single. Hank accepted her offer without notifying Caz. Furthermore, Caz never received any royalties or songwriting credits for his contributions.
Caz launched a brief solo career in the late 1980s, but none of his records made much of an impact and he faded from the hip hop music scene. When attention began being paid to the roots of hip hop in the late 1990s, he resurfaced as a pioneer and began receiving credit for his contributions. He currently works as a celebrity tour guide for Hush Hip Hop Tours, a hip hop cultural sightseeing tour company in New York City.
