Wavering Radiant is the fifth and final full-length album by American post-metal group Isis, released by Ipecac Recordings in 2009 and produced by Joe Barresi. It stands as Isis` last full-length album, as the band split just over a year after its release. The album continues Isis` history of lengthy songwriting, yet presents a slight departure from the soft-loud dynamics and post-metal aesthetic which characterized previous releases.
