One nuance in the keyword often confuses fans. Led Zeppelin did not release a new studio album in 2007. Their last studio album was Coda in 1982. The year 2007 refers to the Celebration Day concert (released in 2012 on CD/Blu-ray/FLAC). Some rare compilation sets also span “The Complete Studio Recordings 1969–2007,” but that is a marketing title for the box set that includes Mothership (2007’s compilation) and the live tracks. For clarity: the core studio discography ends in 1982, but the live/compilation era ends in 2007.
