There are four bands that go by the name Laceration- three from the US and one from Australia. The ones from Illinois were Novembers Doom before being known as that, so they play a very slow style of Death Metal, appropraitely called Death Doom.
The Australian band are a melodic metal group who have been together for six years and have just released their second EP, Unwelcome Guests. A thrash band from the bay area also goes by the name "Laceration".

Utrecht, Utrecht Province, Netherlands (2002 - 2009) Utrecht based metalband Led Astray simply plays metal the way the bandmembers themselves like to hear it: a dynamic hybrid of death and thrash and although the band is not religious, there are undercurrents of spirituality in their lyrics. Led Astray was founded in 2002 by guitarists Martijn and Rogier with the intention of creating a refreshing mix of death and thrash in which the two styles complement each other seamlessly without sounding generic or attempting to be original.

There debut album "The Solitude of Man" was released in September 2010 on Feto Records, which is run by Mick Kenney (Anaal Nathrakh) and Shane Embury (Napalm Death/Brujeria/Lock up/Venomous Concept)
