Periphery

Periphery is an American progressive metal band from Bethesda, Maryland (by way of Baltimore, Maryland), formed in 2005 by guitarist Misha Mansoor. The band is known for their heavy, modern, and progressive sound that includes polyrhythmic patterns and soaring melodies. Periphery is also known as one of the forerunners of "djent metal," which is characterized by high-gain, distorted palm-muted guitar sound first created by groups like Meshuggah and Sikth.
After several lineup changes during its history, the band now includes Mansoor, vocalist Spencer Sotelo, drummer Matt Halpern, additional guitarists Jake Bowen and Mark Holcomb, and bassist Adam "Nolly" Getgood. Periphery released their self-titled debut in 2010 and their follow-up, Periphery II: This Time It's Personal, on July 3, 2012. - Wikipedia
