Aaron Dontez Yates (born November 8, 1971), better known as Tech N9ne (pronounced "tech nine"), is an American rapper, singer, songwriter, record producer, actor, and entrepreneur. In 1999, he and business partner Travis O'Guin founded the record label Strange Music. He has sold over two million albums and has had his music featured in film, television, and video games. In 2009, he won the Left Field Woodie award at the mtvU Woodie Awards.
His stage name originated from the TEC-9 semi-automatic handgun, a name given to him by rapper Black Walt due to his fast-rhyming Chopper style. Yates later applied a deeper meaning to the name, claiming that it stands for the complete technique of rhyme, with "tech" meaning technique and "nine" representing the number of completion.
