attleroar started in 2000 at Athens, Greece under the influences of Power Metal/Epic/Classic Metal (mostly from the 80s) in the style of Manilla Road, Omen, Cirith Ungol, Brocas Helm, Heavy Load and Jag Panzer (some of whom they'd later perform with). After a year of rehearsing they decided to record a promo CD, in November of 2001, containing 5 songs of a rehearsal and live, titled simply Promo. Under the membership of Vagelis Krouskas (vocals), Kostas Tzortzis (guitar), Manolis Karazeris (guitar), Chris Remoundos (bass) and Nick Papadopoulos (drums). The response encouraged them to a 7" single Dragonship the following year. Some months after this release, two new members joined the band in the form of Marco Concoreggi (vocals) and Kostas Makrikostas (bass) to replaced Krouskas and Remoundos respectively.
In March of 2003, they entered the studio for their self-titled full-length album. Kenny Powell (of Omen) contributed with his participation on one of the songs. In August of that year 'Omicron Music' released the album. It has recently been announced the band had soon after split.
