The Physical Graffiti album in 1975 came as a surprise to most Led Zeppelin fans with it's longer moodier tunes and uneven texture, but a good surprise to most, ending up being a megahit for the band.  An odd collection of new songs along with older songs they didn't use on previous albums, it makes for one of their more interesting offerings.  We'll roll one of those longer moodier things on today's vault, by request.  Tired of the same ole Zep?  C'mon by for 'Ten Years Gone" around 5:20 or so.  Don't forget, you can listen live on-line!
