XL, KRS-One, and Kool G. Rap. Later that year, he and business partner Travis O'Guin founded the record label Strange Music. 2001–2005: Underground success In 2001, Yates released the studio album Anghellic on JCOR Records. After disputes arose about the promotion of the album, Yates 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). The album debuted number 79 on the Billboard 200. The album's sales are said to have tripled following a campaign, going by the name of "F.T.I." was started by the rapper and his label. The campaign, which asked music listeners to legally download the album free through the artist's own website was in response to the anti-downloading campaign by the RIAA. 2006–2011: Independence and Tech N9ne Collabos In 2006, Yates released the album Everready (The Religion). The following year, he released Misery Loves Kompany. Yates 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, Yates released the album Killer. That September, he exceeded one million album sales over his entire catalog. Yates remarked of the accomplishment that, "It just reminded me of all the work we'd done in the past, up until now [...] I don't think it's sunken in yet. I've been celebrating for the last two days because that's a hell of an accomplishment. I've been planning success all my life. I'm not even a bit surprised, I'm happy about it. That just means I was right." Yates released his second Collabos album, Sickology 101, in April 2009. Yates later performed at the Rock The Bells 2009 Festival and the tenth annual Gathering of the Juggalos. That October, he released K.O.D., an acronym for King of Darkness. The album featured a dark overtone, as Yates 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, Yates 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
