I see what Morrison did as being very difficult to replicate. I don't elevate it as highly as it's been in years past, but I look back at what he did and what's come since and cannot find many replacements. I suppose you could call it early punk attitude mixed with early southern rock mixed with early singer songwriting, but it's really just some dude who didn't give a flip for 5 years. I find that people not giving a flip in the 60's was often much different and more radical than today.
