LED ZEPPELIN frontman Robert Plant has recorded guest vocals for the new album from British modern rockers PRIMAL SCREAM, due in 2013.Speaking to Mojo magazine, Plant said he wants to carry on singing, but doesn't want to start a new band or make a full album. He said: "Everything we did back in those days and everything I have done since has been based on a fresh approach. What's going on? What can I be as a singer that doesn't play much? That's how I see everything: what can I be a part of that's exciting? And if anybody's got any ideas, then I'm always up for it." He added: "I sang a bit on the PRIMAL's stuff because I think their references on looking back on the glorious past and the way they bring them into the contemporary world are fantastic." Plant previously played harmonica on PRIMAL SCREAM's 2002 song "The Lord Is My Shotgun", which was featured on the band's "Evil Heat" album.
