The Apex Theory was formed in 1999 by Armenian-American musicians Ontronik "Andy" Khachaturian, Art Karamian and David Hakopyan (first drummer and bass player of Soil / System of a Down respectively), following Khachaturian's injury and subsequent departure from System of a Down.
The following year, they signed with DreamWorks Records,[5] releasing their second EP The Apex Theory on October 9, 2001.
[1][2] The Michigan Daily writer Sonya Sutherland wrote, "The Apex Theory combines a heavy drum support, melodic guitars and honey sweet vocals to provide an entertaining and emotional message.
And the off-kilter rhythm, skittering drums, whirlpool guitars and aggressive vocals of 'Shhh ... (Hope Diggy)' are a perfect taster for the band's debut album".
[3] Deseret News said that "Apex Theory's progressive punk mixed exotic music signatures with psychedelic rock".
