UMUR "D.T.P." (or "Death to Posers") is the first demo cassette tape by US, California based thrash metal act Sadus. The demo was independently released in 1986. It features 6 tracks and a full playing time of 17:45 minutes. Some of the tracks would make it unto Sadus debut full-length studio album "Illusions (1988)", while others are exclusive to this demo. The tracks from the demo are also available in remastered versions on the "DTP Demo 1986" compilation released through Hammerheart Records in May 2003.

Stylistically the music on the demo is frenetic high energy thrash metal delivered with bite and aggression. Darren Travis has a high pitched raw voice and an almost hysterical delivery, which is quite extreme and probably a bit of an aquired taste, but it surely sets Sadus apart from other contemporary artists. The instrumental part of the music isn´t overtly original but it´s well played and the songwriting is solid too.

For a 1986 thrash metal demo, the sound quality is pretty great, and the material is well presented in a raw and detailed sound production. So overall "D.T.P." is a promising first release by Sadus. Being familiar with the band´s later material it´s actually quite interesting how much of their "trademark" sound is already in place this early on. Steve DiGiorgio´s bass is not as high in the mix as on later studio output, but other than that, this sounds like "classic" Sadus through and through. A 3 - 3.5 star (65%) rating is deserved.
