On Thursday, Led Zeppelin will stream the 40th anniversary edition of Physical Graffiti, which has been re-mastered and will be re-released Tuesday (February 24th), on the same date it first appeared in 1975.

Thursday’s online event will include the album in its entirety, bonus tracks and a question-and-answer session with Jimmy Page from Olympic Studios in London, where parts of the album were recorded. The event gets underway at 2pm ET on Yahoo Live.
