The concept of creating studio recordings that lack the lead vocal has been around for probably nearly as long as recording itself. Many artists, amateur and professional, perform in situations where a full band/orchestra is either logistically or financially impractical and so they use a "karaoke" recording, but they are actually the original artists. (This is not to be confused with "lip syncing" in which a performer mimes to a previously produced studio recording with the lead vocal intact.) (source)
