is an American rock band from Irvine, California. The group was founded in 1998 by guitarist/vocalist Dustin Kensrue and guitarist Teppei Teranishi while they were in high school.
Early in their career, the band was known for fast, hard music based in heavily distorted guitars, prominent lead guitar lines, and frequent changes in complex time signatures.' This style is exemplified on their second album, The Illusion of Safety (2002) and their third album The Artist in the Ambulance (2003). Their fourth album Vheissu (2005) made significant changes by incorporating computerized beats, keyboards, and effects into songs that were often slower and less technically difficult. Their fifth effort was a quadruple album entitled The Alchemy Index (2007/2008), released as two sets of two CDs that together make a 4-part, 24-song cycle. Each of the four 6-song EPs of the Alchemy Index features significantly different styles, based on different aspects of the band's musical aesthetic which reflect the elemental themes of fire, water, air and earth, both lyrically and musically.
Throughout the band's career, Thrice has been known to donate proceeds from album sales to charitable or non-profit organizations, including novelist Dave Eggers's charity 826 Valencia, which promotes literacy and aids teens with creative writing. In return, Eggers created the cover art for Vheissu.
