Is a Mac book an instrument ?

Allison Krauss would cringe at autotune, I've seen her in concert a couple of times now and she dont need it! Voice of an angel.

I'm not a fan of country music but I can appreciate the talent of someone utilises their natural voice. Anythings better than the robots you hear on the radio.

Bluegrass/folk is her real genre, less country, but I know what you mean! Where I'm from there is a very real and divisive difference! Bluegrass is the music of my people. Either way, you're right, no autotune required, voice is very pure :)
