Tech N9ne / E-40

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.

Earl T. Stevens (born November 15, 1967), better known by his stage name E-40, is an American rapper and actor. He is a founding member of the rap group The Click, and the founder of Sick Wid It Records. He has released twenty-eight studio albums to date, appeared on numerous movie soundtracks, and has also done guest appearances on a host of other rap albums. Initially an underground artist, his 1995 solo album In a Major Way opened him up to a wider audience. Beginning in 1998, he began collaborating with more mainstream rappers outside the Bay Area. He rose to even higher mainstream popularity in 2006 with his single "Tell Me When to Go" which was produced by Lil Jon.
