Aaron Dontez Yates (born November 8, 1971), better known by his stage name Tech N9ne (pronounced Tech Nine), is rapper from Kansas City, Missouri. In 1999, Tech N9ne and Travis O'Guin founded the record label Strange Music. His stage name originated from the TEC-9 semi-automatic handgun, given to him by rapper Black Walt due to his fast rhyming Chopper style. Tech N9ne 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.
Early in his career, Tech N9ne was a member of a group formed in 1991 called Black Mafia. He saw glimpses of success in the group 57th Street Rogue Dog Villians with their single "Let's Get Fucked Up." As a member of the group Nnutthowze, Tech N9ne signed with Perspective Records in 1993. However, the group disbanded soon after being released from the label. Tech N9ne signed with Qwest Records briefly before moving to JCOR Records. In 2001, Tech N9ne released the studio album "Anghellic" on JCOR Records. After disputes arose about the promotion of the album, Tech N9ne and his label severed ties with the JCOR with a deal that allowed them to retain the rights to the album. The next year, he released "Absolute Power", under a 50–50 joint venture between Strange Music and M.S.C. Music & Entertainment (which was founded by former Priority Records head Mark Cerami).
In 2006, Tech N9ne released the album "Everready: The Religion". The following year, he released "Misery Loves Kompany". Tech N9ne announced that the album was the first in a series of "Tech N9ne Collabos" albums that feature a wide range of guest appearances. The following year, Tech N9ne released the album "Killer". That September, he exceeded one million album sales over his entire catalog. Tech N9ne released his second Collabos album, "Sickology 101", in April 2009. That October, he released "K.O.D.", an acronym for King of Darkness. The album featured a dark overtone, as Tech N9ne was dealing with the illness of his mother. An EP of new songs over unused beats from the "K.O.D." album was released in 2010 as "The Lost Scripts of K.O.D.". Later that year, Tech N9ne released his third Collabos album, "The Gates Mixed Plate". In October, he released his second EP "Seepage". On December 23, he released his first mixtape "Bad Season", which was later released in retail CD form with a modified track list and without DJ Scream. On June 7, 2011 Tech N9ne released "All 6's And 7's".
On September 18, 2012, Tech N9ne released an EP titled "E.B.A.H". (Evil Brain Angel Heart). He was featured on the song "Edge of Destruction" (which also features Twista) that appears on Machine Gun Kelly's first studio album "Lace Up". On October 30, Tech N9ne released an EP titled "Boiling Point". He announced his thirteenth studio album would be titled "Something Else" and would be released on July 30, 2013. The first song released from the album would be "B.I.T.C.H." an acronym for Breaking In To Colored Houses which features rapper/singer T-Pain.
