I usually try to link to a studio version of each song I post about, because if you've not heard the song before, I want to at least give you one chance. And then maybe you'll want to own a superior audio version at some point.

I make an effort to avoid linking music videos for songs, just to limit distractions from what the song really is versus what maybe appealing and marketable things are being done on a visual companion to the song to drive sales.

And I usually avoid linking to live performances, just because the studio versions are the fullest experiences of most songs on my list.

For "Communication Breakdown," that last rule breaks down. There is nothing I can tell you about this song without showing you the flailing drum performance of John Bonham live on this video. Throw in an absolutely peak power Robert Plant vocal, and you see the two unvarnished, unschooled talents that propelled Led Zeppelin past any competition.

The music otherwise is pretty simple to understand. The same concept worked again on the next album with "Whole Lotta Love": Find one excellent down-strummed blues riff and pummel the world with it.
