Anyone know where to find early south park coalition music?

Someone tried to say esham predates ganksta nip and as far as debut solo albums that's true. But I know ganksta nip did stuff with S.P.C. which they founded in 1987 and that predates esham by at least 2 years. However I can't find any albums by S.P.C. earlier than 2002. Unless it's like the same thing three 6 Mafia did where they have albums which are compilations of old mixtapes. But since the official compilation albums for those mixtapes was released later that's just what the Internet says.
