I think Led Zeppelin and Richard Wagner possess some surface similarities. Both produced emotion-laden and dramatic music which was mesmerizing, enthralling and almost hypnotic. Both were hugely popular and influential in their heyday and continue to be so today. Both possess large, loyal fanbases. Both were accused by their critics of producing music which was self-indulgent, bloated, authoritarian, and even "dangerous." Once, Plant even compared Page to Wagner. I don't mean to overstate the similarities between Zep and Wagner -- there were obviously many huge differences between the two -- but I thought these similarities were worth noting.
