Allegaeon (pronounced: uh-lee-juhn) was formed in 2007. In 2008 they released their 4 song, self-titled EP and quickly gained attention of Metal Blade records.

July 20th, 2010 brought Allegaeon's debut album Fragments of Form and Function (FOFAF). FOFAF was recorded in Denver at Flatline Audio with Dave Otero (Cephalic Carnage, and Cattle Decapitation) Metalstorm.net lists Allegaeon's debut album, FOFAF, as the #4 rated death metal album of all time (by the websites rating standards). FOFAF was critically acclaimed by many and catapulted the band out of obscurity and into the ranks of metals elite new bands.

In January 2012, the band traveled to Southern California and entered the studio with Daniel Castleman to begin work on their follow up record titled Formshifter, which peaked at #29 on the Billboard heatseekers chart. It also marked the last record guitarist Ryan Glisan would do with the band.

Allegaeon released their third full-length album Elements of the Infinite on June 24, 2014. Once again recorded at Flatline Audio with Dave Otero, the band expanded their classical music side with the addition of orchestral passages. With the added talents of guitarist Michael Stancel, and drummer Brandon Park, the music videos for "1.618" and "Threshold of Perception" showed the bands more fun loving personalities noting "we take the music seriously, but not ourselves". Elements debuted at number 25 on the Hard Rock Billboard chart.

The band’s latest album Proponent For Sentience, released in 2016, marked the first with vocalist Riley McShane, and included guest appearances from Bjorn "Speed" Strid (Soilwork) and Benjamin Ellis (Scar Symmetry). The album showcased McShane's dynamic vocal range with the first appearances of throat singing, pitch screaming, and clean vocals. Metal Injection reviewed the album at a 9/10, and the album reached number 11 on the US Hard Rock Billboard chart, and number 33 on the US Rock chart.
