Music fans waiting for the platinum-selling, Grammy dominating team of Robert Plant and Alison Krauss to reunite for a follow-up to their 2007 album 'Raising Sand' will have to wait a while longer.

According to a Rolling Stone interview, the duo did indeed enter the studio to create a second album, but according to the former Led Zeppelin singer, "The sound wasn't there. Alison is the best. She's one of my favorite people. We'll come back to it."

Plant has a well-documented history of following his creative muse -- regardless of how it will affect his involvement with his various bands. Ask his fellow surviving Zeppelin partners Jimmy Page and John Paul Jones, who reportedly were expecting a full tour following the band's one-off 2007 reunion show. (Regardless, we stand by Plant's decision to not do it -- the late, great Zep drummer John Bonham cannot be replaced.)

So, while Plant takes yet another great band on the road (see our Band of Joy tour preview here), it doesn't seem as though Krauss is sitting home waiting for the phone to ring. She has reportedly recorded a new album with her band, Union Station, which is scheduled for an April 2011 release.

Besides, you can still listen to 'Raising Sand' whenever you want, or check out this video of the duo performing 'Please Read the Letter,' a song Plant did (in a more lively version) with his old pal Page about a decade ago.
