Each to their own, I suppose.
I've never been much of a Dead fan because their music doesn't really move me. However, I totally repect their relentless dedication (no pun intended) to their own muse, which is a quality sadly lacking in music today. They are one of the few bands that made a career out of doing exactly what they wanted - and who among us wouldn't wish for the same thing?
Their live vocals are brutal sometimes, for sure, and the improvs don't always work, but I would rather listen to the Dead for their honesty and integrity than some Pro Tools fabrication. Pro Tools (when used to fix mistakes) is to music as Cheese Whiz is to food. Safe, but no flavor. I've just finished a gig with a band leader who insisted that we rehearse while listening to a click track. It made our time more prefect, for sure, but for me it also sucked the life right out of our groove. Music is the most perfect form of human communication, and anything that sucks the humanity out of it is a bad thing.
Humans make mistakes, you know - it's o.k. For me, perfection in music is a means, not an end. If it feels good, if it grooves, if it speaks to the soul - it's music...even if it isn't perfect.
Man, am I in a bad mood. Time to go hit my open A string over and over and let it ring until I find peace.
