Periphery is an American progressive metal band from Bethesda, Maryland, formed in 2005. History
Formation and Lineup Changes (2005 - 2009)
Periphery was formed by guitarist Misha Mansoor in 2005. He slowly gained a reputation on the Internet, primarily via a regularly-updated Soundclick account, Meshuggah and John Petrucci forums, and the sevenstring.org message boards. Before and during Periphery's tenure in the metal scene, Mansoor developed a reputation for doing his own audio production, the majority of which was performed with a home computer and a Pod XT during this period.

Formed in 2003, The Final Sigh have taken massive steps in the underground and mainstream music channels. From self financed EP releases to major exposure which includes splits with Corpo's RSJ, stateside publication with Rotting Corpse Records' Raw Aggression compilation and maintaining a presence on Chicago's Metalworks Radio. This was followed up with the critically acclaimed debut album "If You're Not Part of the Solution, You're Part of the Problem" released worldwide in May 2005 through Anticulture Records.

Tired of former bands and projects, five Berlin citizens formed War from a Harlots Mouth between the end of 2005 and spring 2006. They combine the technical elements of mathcore with deathcore and a blend of jazz. After releasing a Split-CD with Molotov Solution from Las Vegas on Twelve Gauge Records, the quintet signed to Lifeforce Records for the release of their full length debut album “Transmetropolitan” in 2007.

There are 6 bands named Lethargy: 1) Smooth, technical death metal from Rochester, NY. Today Is the Day, Sulaco, and Mastodon all feature alumni of Lethargy at some point. 2) Spanish electronic band with sensual female vocals. It was formed in Madrid in 1992 by Mayte Cruz and Julio Tomé.
"Hailing from Madrid, the duo Lethargy is described as a 21st century version of Massive Attack and Autechre, with a touch of Lassigue Bendthaus.
