I got into the Dead late in my musical life - I was in my early 30s and in law school back in the mid-late 1980s before I really sat and listened. American Beauty first drew me in, but I eventually settled on the 1970s as my favorite era. Love Europe '72, One From The Vault, etc so I guess I'd have to say the Keith and Donna era is probably my favorite. JG was playing so beautifully at that time and the telepathy in the band was amazing.
