Keller has been performing in gay porn since 2004 and during that time has continued to work as an Artist. Keller's two most notable art projects include Pieces of Eight and Everything But Lenin, both collaborative performance pieces. Pieces of Eight involved multiple projects and multiple collaborations while Everything But Lenin involved giving away all of his earthly possessions with the exception a large metal plaque of Lenin and was precipitated by an eviction notice presented to residents of his Baltimore apartment complex in March 2014. Those who took part, received a signed certificate as project participants.
In 2012, Keller appeared in a masquerade-themed music video for the song "After Dark", by dance artists Undercover. And, in his 2013 music video for "Cannibal", Natti Vogel enlisted Keller to play a hooded witch to his tempted Hansel in a recreation of Hansel and Gretel.
In 2013, Keller collaborated with Artist Cameron Stalheim on a project called Myth as Object, which resulted in a 2014 exhibit as Stalheim's MFA graduating thesis at the Maryland Institute College of Art. Keller's body was cast in silicone to create a thirty-foot long merman sculpture in his likeness.
With $45,400 that was raised in a 2014 Indiegogo campaign, Keller began shooting his own art/porn project, Colby Does America, a series of porn videos being filmed in every state across America as well as several provinces in Canada.
Keller voted for Donald Trump in the 2016 United States presidential election, stating, "I’m going to vote for Trump! I think he’s a destabilizing force. I’m skeptical of him, too, and who exactly is behind Trump. But given that there’s eternal dissent in the Republican Party, that leads me to believe that whatever he represents might be a destabilizing force. And he’s made a lot of overtures to Russia and China, which in some ways could be thought of as an encouraging thing. I don’t support or endorse any of Trump’s policies. I just think it’ll escalate the Problem, which is the best we can hope for."
In 2017 he starred in the third season of EastSiders.
