'In Your Honour' is the fifth studio album by Foo Fighters, released on June 14, 2005 by RCA Records. It is a double album, with one disc containing heavy rock songs and a second disc with mellower acoustic songs. Frontman Dave Grohl decided to do a diverse blend of songs as he felt that after ten years of existence, the band had to break new ground with their music. The album was recorded at a newly built studio in Northridge, Los Angeles, and featured guests such as John Paul Jones, Norah Jones and Josh Homme. The lyrics deal with both resonating and introspective themes, with a major influence from Grohl's involvement on the campaign trail with John Kerry during the 2004 presidential election.
