"The Two Most Influential Cult Bands in Rock History"

"The late '60s was a fertile time for rock, period. You could say it's hardly a shock that two pioneering underground rock groups debuted the same month. But there is something strange and special about two bands who inspired decades of underground admiration and imitation debuting within less than a week of each other. They might rule vastly disparate realms of rock, but both have established themselves as the kings of cult for decades to come."

Joe Lynch at Billboard links the Velvet Underground to the Grateful Dead.
