Biography
Nahum Rabay is a Brazilian Jiu Jitsu red belt (9th degree) and a student of one of the Gracie Jiu Jitsu founders, George Gracie. Aside from being an important musician and a highly regarded figure in Sao Paulo's BJJ, Nahum Rabay, curiously, was directly involved in the first case of "creontagem" in Jiu Jitsu (a student leaving an instructor or team for a direct rival), wich happened in 1954, when the Helio Gracie student, Guanair Vial, decided to abandon the Gracie Academy to move to George Gracie's camp after being dominated by the smaller Nahum Rabay at an important Jiu Jitsu challenge.
