One of the headings is "The Ballad of Sickabod Sane", and a quick Google search turns up his MySpace page: http://www.myspace.com/sickabodsane
An article in Flak Magazine[1] describes him as "a popular MC from the Manhattan club scene."
You don't specify what you mean by "a good career," but it would appear that he's not reached the Cristal-filled-hot tub stage in life yet.
I did enjoy his songs, though.
