Led Zeppelin continue teasing us with bits and pieces from the upcoming reissues of their first three albums. Yesterday (May 2), they released a new trailer video for 'Led Zeppelin II.'

Scored by the rough mix of 'Whole Lotta Love' that is one of the previously unheard bonus tracks, the one-minute trailer features the album's artwork, some concert footage and plenty of memorabilia. The video is embedded above.

Arriving on June 3, the reissue of 'Led Zeppelin II' includes a second disc with alternate mixes of five songs, the backing tracks for two more and a never-before released song, 'La La.' The set will be available in CD, vinyl and digital formats, with a Super Deluxe box that includes a 70+-page book about the album and a high-quality print of the original album cover.

The group have already given us a few tastes of what's in store. Last month they uploaded a live version of 'Communication Breakdown' from the 'Led Zeppelin' set, as well as a bit of their cover of the Big Bill Broonzy song 'Key to the Highway,' which will be featured on the 'Led Zeppelin III' reissue bonus disc.
