The hyper-love of new technologies is also a theme. Thornton performed and released two albums under the alias. The character was murdered by Dr. Dooom on Thornton's 1999 album "First Come, First Served", and was briefly revived before once again being killed on Thornton's 2008 album "Dr. Dooom 2", in response to the release of "The Return of Dr. Octagon", an album largely produced without Thornton's involvement. Kool Keith reunited with Dan the Automator and DJ Qbert to release "" on April 6, 2018.
