Santa Killa Crew, often abbreviated SKC, was a horrorcore group from Poland. They released music on their own label, Loonatic Productions.
After releasing a number of singles in 1999 and 2000, followed by their debut album, “The Greatest Killa Show,” the group changed their style and line-up to include a drummer, a guitarist and bassist, etc.
There was also “The First Star” a Christmas single. I have the cassette of that and the Greatest Horror Killa.
Does the cassette that you own have a release year on it? What is the year?
