UMUR "Chaotic Destruction" is the second demo release by US, Buffalo, New York based thrash metal act Tirant Sin. The demo was independently released in October 1987. It´s the successor to the February 1987 demo "Desecration of the Graves" and there have been a couple of lineup changes since the last release, as guitarist Cam V. has been replaced by Joe Morelli and vocalist Dennis John Glinski has been added to the lineup to make Tirant Sin a quintet on this release. The vocals on the first demo were handled by bassist Rich Ziegler and drummer Paul Mazurkiewicz, and a permanent and more professional sounding solution was needed.

Tirant Sin formed in 1985 under the Satan´s Angel monicker but soon changed their name to Tirant Sin. Tirant Sin released three demos before morphing into Cannibal Corpse along with members of another Buffalo thrash metal unit Beyond Death.

Stylistically "Chaotic Destruction" continues the aggressive and brutal thrash metal style Tirant Sin initiated on "Desecration of the Graves" but it´s audible that the band have honed their playing skills and that the addition of a "real" singer have boosted their sound. "Chaotic Destruction" also features a better sounding production than the first demo, and overall it´s the step up in quality you´d expect from a sophomore release. The songwriting is still very standard for the genre though, and it´s in that department that "Chaotic Destruction" doesn´t do anything out of the ordinary. A 2.5 - 3 star (55%) rating is warranted.
