Yes, that works to some degree. You just need to be careful that you don't slice things down too thin.
First off, the band should not have so much instrumentation during vocal passages that it buries the vocals. An element of good song writing. Secondly, you can control the levels of those instruments during mixdown. Lowering volume of the most offending ones can help. Lastly, if you still cannot get the vocals to come out, you may need to make use of compression to bring them more forward and in-your-face. If you need help with that, I have made a video to explain how to do it. It is over in the articles section of this site.
I hope this helps.
