313

313 (pronounced 'Three Thirteen') was a pivotal but short-lived heavy metal outfit from the Pittsburgh/Monroeville area, active primarily between 1985 and 1988. Formed from the ashes of the band Discipline, the group featured the formidable vocal talents of Tim Aymar, who would later gain international fame as the vocalist for Chuck Schuldiner's Control Denied.

Their sound is a quintessential example of the mid-80s US Power Metal (USPM) movement, blending the melodic sensibilities of traditional heavy metal with the increased tempo and aggression of speed metal. Despite signing with PARC Records, their debut full-length was shelved due to label instability, leaving their legacy to circulate via the 'Jet Screamer' demo for decades. The band's sound identity is defined by intricate guitar harmonies, a 'galloping' rhythmic foundation, and Aymar's wide-ranging, operatic-yet-gritty delivery. Their historical importance lies in their contribution to the regional Pennsylvania metal scene and as a foundational chapter in Tim Aymar's career. The 2019 Divebomb Records compilation finally consolidated their studio output, cementing their reputation among collectors of rare 80s metal.
