Unheard Led Zeppelin song on album
A previously unreleased track recorded by rock veterans Led Zeppelin for their debut album will finally see the light of day as a bonus track on their final studio album.
The track, called Sugar Mama and described as a "frenetic blues jam", was recorded in 1968 shortly after guitarist Jimmy Page put the band together from the ashes of the defunct r'n'b band The Yardbirds.
Led Zeppelin's last three studio albums - Presence, In Through The Out Door and Coda - have been remastered by Page and will be released next month.
The reissue of 1976's Presence will include a previously unheard instrumental called 10 Ribs & All/Carrot Pod Pod (Pod), while Coda will feature an unreleased instrumental called St Tristan's Sword recorded for their third album.
It also includes two tracks recorded by Page and frontman Robert Plant during a 1972 trip to India to perform with the Bombay Orchestra.
The band, famous for their powerful stage shows and outrageous backstage behaviour, played to thousands of fans and sold millions of records in their 1970s heyday.
Fo unding members - Page, Plant and bass player John Paul Jones - famously reunited on stage in 2007 along with Jason Bonham, the son of late drummer John, at a tribute concert for Ahmet Ertegun, the founder of the band's label Atlantic Records.
