Grails are an American instrumental rock band from Portland, Oregon.

Initially the band 'Laurel Canyon' formed to play one show on a whim. In 2003 the band changed its name to Grails, just before the release of their first full-length album. They adopted a louder, more aggressive style, often switching instruments with each member writing songs that saw them branching out to increasingly disparate styles. They live in Portland but rarely play live in their hometown.

The group produced two releases while signed to Neurot Recordings - The Burden of Hope and Redlight. Additionally, they recorded the album Black Tar Prophecy, a collection of earlier EPs, for the Important Records label in Massachusetts. In 2006, they signed with indie label Temporary Residence Limited, who released their current album, titled Burning Off Impurities in March 2007.
