2000s

The year 2003 saw the release of the triple live album How the West Was Won, and Led Zeppelin DVD, a six-hour chronological set of live footage that became the best-selling music DVD in history. In July 2007, Atlantic/ Rhino and Warner Home Video announced three Zeppelin titles to be released that November: Mothership, a 24-track best-of spanning the band's career; a reissue of the soundtrack The Song Remains the Same, including previously unreleased material; and a new DVD. Zeppelin also made their catalogue legally available for download, becoming one of the last major rock bands to do so.

On 10 December 2007, Zeppelin reunited for the Ahmet Ertegun Tribute Concert at the O Arena in London, with Jason Bonham again taking his father's place on drums. According to Guinness World Records 2009, the show set a record for the "Highest Demand for Tickets for One Music Concert" as 20 million requests were submitted online. Critics praised the performance and there was widespread speculation about a full reunion. Page, Jones and Jason Bonham were reported to be willing to tour and to be working on material for a new Zeppelin project. Plant continued his touring commitments with Alison Krauss, stating in September 2008 that he would not record or tour with the band. "I told them I was busy and they'd simply have to wait," he recalled in 2014. "I would come around eventually, which they were fine with – at least to my knowledge. But it turns out they weren't. And what's even more disheartening, Jimmy used it against me."

Jones and Page reportedly looked for a replacement for Plant; candidates including Steven Tyler of Aerosmith, and Myles Kennedy of Alter Bridge. However, in January 2009, it was confirmed that the project had been abandoned. "Getting the opportunity to play with Jimmy Page, John Paul Jones and Jason Bonham was pretty special," Kennedy recalled. "That is pretty much the zenith right there. That was a crazy, good experience. It's something I still think of often... It's so precious to me."
