I was always curious about whether or not a remaster of a recording such as something early by Charlie Parker gets "re-protected" under copyright laws as a new recording? Does that take the remastered version out of the public domain? Can the earlier issue enter the public domain and exist in tandem? On a different note, I have heard a rumor that states that hip hop reissues of albums from before 1992 (when the new sampling laws went into effect) that are newly re-released can be sued as a new recording for sample infringement. Just curious where all this stands.
