"All My Love" by Led Zeppelin

It is virtually impossible to pick the greatest song from Led Zeppelin's uncharted classics, largely because so many of their well-known songs surprisingly never charted, including "Communication Breakdown," "Ramble On," Dazed and Confused," and even their epic ballad, "Stairway To Heaven."

These legendary pioneers of hard rock did score some top 20 hits with "Whole Lotta Love" (#4), "Immigrant Song" (#16), "Black Dog" (#15), and "D'yer Mak'er" (#20). 

While many associate Led Zeppelin with the gritty and blazing guitar of Jimmy Page and the banshee rock vocals of Robert Plant, some seem to forget how diverse the music of Led Zeppelin was. They effortlessly jumped between hard rock, psychedelic rock, the blues, symphonic rock, and acoustic rock. They should have had more chart hits, but their influence on rock and roll still lives on today.

"All My Love" showcases yet another dimension of the band, a rare and tender moment. The heartfelt song is about the death of Plant's son and rips me up every time I hear it. It is also one of the first to feature synthesizers, played by bassist John Paul Jones.

Led Zeppelin faced another tragedy when drummer John Bonham died in 1980, at which point they decided to disband.
