3 Inches of Blood is a Canadian heavy metal band formed in Vancouver, British Columbia in 2000.The band was heavily influenced by the NWOBHM bands of the late 1970s and early 1980s. Their sound is also very thrash-influenced and contains major elements (namely, vocals) of early death and black metal.

Their debut album Battlecry Under a Wintersun was recorded in 2002 on the Megarock Records label. This release went by almost unnoticed until the band's UK distribution label decided to put them on as a support slot for a tour with platinum rock band The Darkness. This exposure gained them much critical attention and acclaim in the world of underground metal, and they were signed up by major label subsidiary Roadrunner Records in 2004.

The band toured the United States during January and February 2007 in support of Cradle of Filth with The 69 Eyes and in March toured the UK with Biomechanical. In October 2006, the band opened a show for Iron Maiden during the United States leg of their 2006 A Matter of Life and Death World Tour. The show was at the Verizon Wireless Amphitheatre in Irvine, California. On March 22, 2007, the band was confirmed to play the second stage at Ozzfest.

Shane Clark is one hell of a guitar player. If any player defines heavy metal rhythm playing it's Shane. Learn from him!!!!!
