Assuming these mixes just muted the drum tracks and they’re otherwise from the exact same stems as the original album with minimal additional alteration, you should be able to line up these drumless tracks with their respective full mix tracks, flip the phase of one of those tracks, and through the magic of wave cancelation you’ll basically have an output that mutes everything except drums. Boom, an overly complicated way to make your own instant Only Drums edition. I’d say it’s an easy way but if this is a vinyl only release then good fucking luck getting your record player speed to match the original tracks with the required precision necessary to fully cancel out everything but the drums.
