I have Machine Head on vinyl and the anniversary CD release.
:^)
That other track is from “The Book of Taliesyn,” which is an interesting album.
Check out this incredible relatively recent live version of Pictures From Home, with huge orchestral accompaniment. Stick with it, it takes about 2 minutes to get going.
