Unheard Led Zeppelin tracks to be released

Popular 1960s rock band Led Zeppelin is set to release more than 10 unheard songs from their archive, including one of its oldest tracks, "Sugar Mama".
The frenetic blues jam was recorded in 1968 at the Olympic Studios along with "Baby Come On Home" during sessions for the band's self-titled debut album, reported The Independent.
The unreleased rollicking instrumental 1970 track, "St Tristan's Sword", in the re-issue of the band's final three studio albums, "Presence" (1976), "In Through The Out Door" (1979) and "Coda" (1982), will also be released.
Other unheard songs to be released include five mixes from the band's 18-day sessions at Musicland Studios in Munich.

The band will also unveil recordings of songs "Four Hands" ('Four Sticks') and "Friends" from Jimmy Page and Robert Plant's 1972 trip to India where they performed with the Bombay Orchestra.
The second wave of Led Zeppelin activity raises hopes that the heavy rock pioneers may tour once again after their acclaimed sell-out 2007 reunion gig at the O2 Arena.
