There is more than one artist/group using the name Circadia. The following bio describes the heavy prog/post-metal group from Burlington, Iowa, US.

Circadia solidified it's current lineup in early 2008 and immediately started working on new material to follow up the full length album "Descent".

The new material picks up where “Descent” leaves off, moving in a heavier and more technically complex direction while still managing to focus on songwriting.

Circadia is a band that refuses to be pigeonholed by any particular genre. They simply cannot be classified as a “metal band” or a “rock band” or whatever the buzz word of the week might be. Often combining crushing heaviness, beautiful melody and experimental ambience all in the same track, Circadia has been compared to Tool, Pink Floyd and The Mars Volta. Read more on Last.fm.
