I don't relish being negative amongst all the good vibes The Vault puts out, but has anyone else noticed that virtually everything Crosby, Stills, Nash, and Young did was out of tune, including both vocals and instruments? It's so consistently true, that I am beginning to think they knew it at the time and it was just part of their signature. This did jam out at times though and the songwriting is some of my favorite stuff. Southern Man is particularly hard on my ears.
