Webster's first solo full-length project is a mixtape titled Owl Pharaoh, which was set to be released as a free download in 2012. However, the project was delayed, and was announced to be slated for a later release. The project was later re-created by Kanye West and Mike Dean, and was then again delayed for sample clearance issues. In promotion Webster would release the track, "Blocka La Flame", a remix of fellow GOOD Music label-mate Pusha T's single "Blocka" (which features production and vocals from Scott). The song was produced by Young Chop, with additional production by Webster himself, alongside Mike Dean. On March 22, 2013, Webster released the music video for a song titled "Quintana", set to appear on Owl Pharaoh. The mixtape's version of the song features guest vocals from fellow American rapper Wale, while the production was handled by Webster himself, alongside Sak Pase and Mike Dean. On March 27, XXL revealed that Webster was a member of their Freshman Class of 2013. On March 29, 2013, following his interview with British disc jockey, DJ Semtex, Webster premiered a snippet of his commercial debut single, titled "Upper Echelon", featuring 2 Chainz and T. I. On April 2, 2013, Webster stated Owl Pharaoh was his official debut mixtape and would be released on the iTunes Store on May 21, 2013. On April 23, 2013, "Upper Echelon" was sent to Urban contemporary radio. The EP was released for free download.
