In Your Honor is the fifth studio album by American rock band Foo Fighters, released on June 14, 2005, through Roswell and RCA Records. It is a double album, with the first disc containing heavy rock songs and the second containing 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 features guests such as John Paul Jones (Led Zeppelin), Norah Jones, and Josh Homme (Queens of the Stone Age). Its 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. It was the first album to feature keyboardist Rami Jaffee, although he would not join the band as full-time member until 2016.
