Joan Baez - Do I just not get it?

Hi,

I'm a relatively young music/audio guy (24). I recently bought a remaster LP of Joan Baez "In Concert" which I've heard is a great album, both musically and soundwise.

This is my first exposure to Joan Baez - and not meant to offend fans... But I could not make it past song two. Now I love singer/songwriter music, and certainly enjoy female vocals and acoustic guitar... but her voice! It is unlistenable! She uses so much vibrato and sounds like a sheep... baaaaaaa... Stevie nicks can at least get away with being a sheep because she has the rock music to keep the attention away... but joan Baez - How do you guys enjoy listening to this stuff? The vibrato is terrible!
