 Another guest was guitarist Pat Smear, who had been a bandmember from 1995 to 1998, and a guest musician on the tour for "In Your Honor".Smear, who has since been reinstated as a full-on member, described his participation as "the oddest recording experience I had with Foo Fighters" given he had no input in composition and was "going in and playing on a song that was already written".This is their first Foo Fighters' album, since "The Colour and the Shape" (1997) to featured Smear, despite he's become as an official members of the band in their next album "Wasting Light" (2011).
