For some reason I find the possibility of a bunch of studio single tracks to be remote. I hope not because it would make for some very interesting listening. You did ask the right question are they out there in some new release?
Classic rock vocal-only remakes
The other day I heard Mic Jagger belt out "Gimme Shelter" on my favorite morning radio talk show. Difference is there was no accompaniment,just his voice. This was the original studio recording. I had no idea how much was actually going on with his voice till now. It sounded absolutely awesome! Apparently it is the intro for a new computer game that has recently debuted. So I'm wondering if anyone's aware of such a compilation or otherwise of classic tunes by our favorite artists. What a terrific new and refreshing way to hear those old tunes.
