Led Zeppelin have announced two new releases. The first is a 50th anniversary edition of the band's sixth album, Physical Graffiti, and the second is a live EP recorded at the band's Earl's Court shows in 1975 and at Knebworth in 1979.
Fans hoping for previously unreleased material to emerge from Jimmy Page's archive may be disappointed. While the four live tracks haven't been available on CD/vinyl/digital before, they all featured on the 2003 DVD Led Zeppelin, which also included footage shot at London's Royal Albert Hall in 1970 and at New York's Madison Square Garden three years later.
