"London Calling" is one of those timeless songs that can't help sending a shiver up your spine anytime you hear it and the double album it lent its title to is, for many, the quintessential Clash album. To celebrate 25 years since its release, "London Calling" has been re-issued as a special CD/DVD pack. The original album, in its entirety, together with unreleased tracks from the same period, is on Disc 1, with previously unreleased sessions from the Vanilla studios (prior to the album's recording), on Disc 2. These raw demos are mainly of interest to serious Clash fans, but some unfocused jams do offer insight into the development of certain key songs.

The DVD contains live Clash footage, and a short documentary by Don Letts on the recording of the album. This illuminates the band's dedication to their craft and also producer Guy Stevens' method -- smashing chairs in the studio as a way of obtaining "maximum energy" from the band.
