Wondering what Bohemian Rhapsody by Queen would sound like if only Freddies solo vocals and the piano were left over I found this video here:

Blown away first I quickly noticed that the audio track has compression artefacts which can be heard easily + it's a mono mix only.
After quite some time I finally got round to recrating the stripped down mix heard in the original video.

To sum it up: Here you have Bohemian Rhapsody only containing Freddies solo vocals and the piano track mixed down in stereo.
It's basically a quality upgrade over the original video.
Silent parts were completly muted to reduce leakage as much as possible.

Those of you unsatisfied with the mix can download the edited source files I used + the complete multitrack files and try to mix it yourself:

Just open those files in Audacity, Audition or any audio editing tool you like.

Enjoy :)
