A stereo track with vocals? It's all mixed together. What has been joined by ProTools...
At best, with one of the "vocal eliminator" programs, you'll get a hollow-sounding track with some leftover echo of the vocal.
That's how the vocals get 'removed' -- it's a phase/polarity mid-side trick to wipe the center channel.
Maybe for a cheap practice track, but not something I'd perform with for a paying gig.
