 Echoes , Silence , Patience & Grace is the sixth studio album by rock band Foo Fighters , released on September 25 , 2007 by RCA Records . The album is noted for a blend of regular rock and acoustic rock tracks with shifting dynamics , which emerged from the variety of styles employed on the demos the band produced . It also marks the second time the band worked with producer Gil Norton , whom frontman Dave Grohl brought to fully explore the potential of his compositions and have a record that sounded different from their previous work . Grohl tried to focus on songs with messages that resonated on the audience , writing reflective lyrics which drew inspiration from the birth of his daughter .
