Tracks like the crunching “Houses of the Holy” (intended as the title track for their 1973 album) and the loose and lyrical “Down By the Seaside” (written in 1970 and reworked for the group’s fourth record, but ultimately not included) may have been meant for other projects, but they easily meet the band's exacting standards. While each of those first five records was created during a concentrated period of recording, much of the sixth, the double LP Physical Graffiti, drew from material developed at earlier sessions.
Led Zeppelin were on a tear in the early part of their career, releasing a streak of riff-driven albums between 19 that set a new standard in hard rock.
