These are simply great to hear.
As Kirk said, it may ruin the magic for some. Staying away then would be the best course.
However, for many, it is simply telling and great to hear. I am an amateur musician, and when recording I am always concerned with my bass playing. Hearing Myung play is great, because during a full mix you cannot fully hear the various sounds in his playing. So it may sound sloppy to many, but actually it is real sounding and normal. Now I know Geddy Lee, when isolated, would probably sound the same thinking of 'Moving Pictures' tone.
I also agree with Kirk about bands having the courage to release these. Although they are still produced, it does lend to more open analysis.
It also really shows how much JM backs up and thickens JP's sound and tone.
