Formation and Conclusion of an Age (2000–2009)

Sylosis was formed in 2000 by guitarist Josh Middleton and bassist Carl Parnell, who began playing extreme metal with friends from school. Sylosis released a couple of EPs; 2006's Casting Shadows and 2007's The Supreme Oppressor in the UK on 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×Conclusion of an Age24 October 2008 · Studio albumSpotifyYouTube Music (search)Tracklist · 12 tracks1Desolate Seas1:062After Lifeless Years4:573The Blackest Skyline4:584Transcendence4:305Reflections Through Fire4:306Conclusion of an Age5:397Swallow the World5:558Teras5:209Withered4:3710Last Remaining Light7:3711Stained Humanity4:3012Oath of Silence5:29, in October 2008.
Middleton remarked on the style of Conclusion of an Age, "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." After recording their debut studio album, guitarist Gurneet Ahluwalia was replaced with ex-Viatrophy guitarist Alex Bailey in time for an early 2009 European tour with The Black Dahlia Murder, Cephalic Carnage and Psycroptic.
Sylosis were an opening act on the third stage at Download Festival in Castle Donington, along with appearances at the New England Metal and Hardcore Festival, and an opening slot on the Bohemia stage at Sonisphere Festival. A UK headline tour was announced for October/November 2009, but was cancelled when the band were offered an opening slot on the DragonForce UK tour in November/December 2009.
