Formation and Conclusion of an Age (2000–2009)

Sylosis was formed in 2000 by guitarist Josh Middleton, the brother of actress Tuppence Middleton, and bassist Carl Parnell who began playing extreme metal with other friends from school.^[2] Sylosis released a couple of EPs; 2006's Casting Shadows and 2007's The Supreme Oppressor in the UK on a small indie label, In at the Deep End Records. In December 2007 Sylosis signed with Nuclear Blast Records, and they released their debut album Conclusion of an Age in October 2008.^[2]

On the style of their debut album, Conclusion of an Age, Middleton remarked, "The foundation of our sound is old school Bay Area thrash. We don't downtune and we don't play breakdowns. We do like to incorporate lots of different metal styles and textures into our music. We like make all of our songs really epic. We like progressive stuff, brutal stuff and melodic stuff."^[3] After recording their debut studio album, guitarist Gurneet Ahluwalia was replaced by ex-Viatrophy guitarist Alex Bailey, ready for the early 2009 European tour with The Black Dahlia Murder, Cephalic Carnage and Psycroptic.
