Ogre formed in 1999[1] when Ross Markonish and Will Broadbent grew tired of their current prog/drone/trance band, Hello Monster, and decided to start a 70s hard rock and heavy metal influenced project.

[2] In 2000 they released a six song demo,[1] which led to their debut appearance on Water Dragon Records' Greatest Hits Vol.

Ogre has announced that their 10th Anniversary show, set in their hometown of Portland, Maine for September 2009, will be a farewell for the band.

After their break-up, Will and Ross formed Dementia Five with whom they recorded an album, Revolt in the Fifth Dimension, which remained unreleased until April 2015.

They reunited for one show in 2012, playing their first gig since the split-up at Geno's Rock Club in Portland, Maine together with Iron Man and Revelation on September 1.
