Maybe the 25th anniversary year didn't go *quite* as planned but we were still able to come together for a look back at the last 25 years.

By 1993, Nirvana was in a state of disarray. Having kick-started the grunge phenomenon two years earlier, the band were now keen to return to their roots.

On tour promoting their 2005 studio album 'In Your Honor', Seattle-based rock band Foo Fighters, joined by four special guest musicians, performs an acoustic live show at the Pantages Theater in Los Angeles, California in late August 2006.

Foo Fighters captured over their two sold-out nights at Wembley on 6th and 7th June, 2008.

The band began recording their seventh studio album in August 2010 with producer Butch Vig, who had previously produced the two new tracks for the band's Greatest Hits album. The album was recorded in Dave Grohl's garage using only analog equipment. A documentary on the band's history, Back and Forth, was released theatrically on April 5 along with a live 3-d performance of the album Wasting Light. While most theaters viewed the show in its entirety, some theaters had technical issues and the band rescheduled to have Back And Forth played on April 14, 2011. On April 13, 2011, the band performed the entire album live from Dave Grohl's Studio 606 and uploaded it to YouTube in its entirety.

In this new series, Foo Fighters commemorate their 20th anniversary by documenting the eight-city recording odyssey that produced their latest, and eighth, studio album.
