Age of Unreason (album)

Age of Unreason is the seventeenth studio album by American punk rock band Bad Religion, released on May 3, 2019. It is the band's first studio album to feature guitarist Mike Dimkich and drummer Jamie Miller, replacing Greg Hetson and Brooks Wackerman respectively, and the first one to be produced by Carlos de la Garza, thus ending their collaboration with Joe Barresi, who had produced, mixed or engineered every Bad Religion album since 2004's The Empire Strikes First; Barresi did, however, mix "The Kids Are Alt-Right", which had already been released as a one-off single in 2018.

The release of Age of Unreason also marks the longest gap between studio albums in Bad Religion's entire career, with their previous album, True North, having been released in January 2013. Singles released from the album were "My Sanity", "Chaos from Within" and "Do the Paranoid Style".
