Corey Michael Mixter, better known as Titanic Sinclair, is an American singer-songwriter, producer, photographer and director. He is most known for formerly being a part of the band Mars Argo, and for being a previous creative collaborator of American singer Poppy.

Sinclair was born in February 1987. During college, he and his friends would make comedy videos on the websites iFunny, DigitalFunTown and FirstHourMovies. He met Mars Argo on Myspace in early 2007, and the two later began dating and eventually started the band Mars Argo in 2008. Titanic produced a majority of the band's music, working on the album Technology is a Dead Bird, and the EP Linden Place along with various scrapped/unreleased projects and miscellaneous songs. A second studio album was planned for the band but ultimately scrapped due to the band's break-up in 2014, which was caused by various personal issues between Argo and Sinclair which were referenced in a 2018 lawsuit by Argo.

Sinclair met Poppy in early 2014 after she signed to Island Records and the two would go on to start a relationship. Poppy eventually collaborated with Sinclair on a long series of abstract performance art and promotional videos on YouTube. The two worked together on many songs and music projects together from 2014 to 2019. In December 2019, Poppy released a statement in regards to the end of her relationship with Sinclair. Despite this, she went on to release her third studio album I Disagree the following month which would include 10 tracks co-written by Sinclair.

Outside of the Poppy and Mars Argo projects, Sinclair has also directed several music videos for other artists including "My Leather, My Fur, My Nails" by Stepdad released in 2010, "Got the Bite" by Stepdad released in 2014, "10,000 Emerald Pools" and "Electric Love" by Børns released in 2015, "Washed Up Together" by Knox Hamilton released in 2016, and "Camp America" by Vic Mensa released in 2019. He has also worked with the band Blame Candy, who he has directed many videos for. Read more on Last.fm.
