When The Levee Breaks, 1929. Led Zep’s version probably outnumbers this Kansas Joe McCoy & Memphis Minnie original by at least twenty to one on tumblr. It’s one of many Zep “borrowed” from old blues masters as they made their name in the 60s and 70s. Jimmy Page blamed Robert Plant for not reworking the lyrics, telling Guitar World in 1993 that Plant had thus caused the band “grief” with lawsuits, saying his guitar work was too original to be “nailed” on, but with many of the old blues song lyrics basically unchanged, that wasn’t the case with the words. Personally, I like both versions of this song—Memphis Minnie’s guitar work is great, as is Jimmy Page’s—although in some instances (i.e. “Bring It On Home”) I definitely prefer the old to the new.
