So it's happening. So far, as part of their new subscription service (@ $200).
"Teenage Mutant Ninja Turtles Part II: The Secret Of The Ooze (1991)
Following our 2017 release of the original 1990 TMNT score, we are thrilled to present, for the very first time in any format, the complete TMNT Part II: The Secret Of The Ooze film score by John DuPrez! Sourced from the original 1991 master tapes, and in partnership with Nickelodeon and TMNT co-creator Kevin Eastman, we are so excited to bring you the debut vinyl release of the fan favorite Turtles sequel!"
