Kayo Dot is an avant-rock group originally from Boston, Massachusetts, United States (now based in Brooklyn, New York) that was formed in 2003 by Toby Driver after the disband of maudlin of the Well. They released their debut album Choirs of the Eye on John Zorn's Tzadik label that year.

Its lineup is constantly changing, but has consisted of Toby Driver, Ron Varod, Mia Matsumiya, Keith Abrams, Tim Byrnes, David Bodie, Dan Means and Terran Olson.

The music of Kayo Dot can not be accurately described by the limiting contemporary genre nomenclatures. Their songs involve complex instrumentation (composed by singer and frontman Driver), generally without refrain. They are substantially longer than typical rock songs, often ranging from 8 to 15 minutes in length.

Kayo Dot's second album Dowsing Anemone with Copper Tongue was released in January of 2006.

On May 6 2008, they released their third full-length, Blue Lambency Downward, on Hydra Head Records.

Their fourth album, recorded in June 2009, named Coyote, was released on 20 April 2010 on Hydra Head Records. It was later brought out on vinyl by Taiga Records in November 2010.

Their first EP, Stained Glass, was released in January 2011 by Hydra Head, with very little fanfare. It was later issued on vinyl by Antithetic Records in August 2011, with a "de-mix" of the song on the second side.

Their second EP, Gamma Knife, was self-released digitally via http://kayodot.bandcamp.com in January 2012. Antithetic Records produced a vinyl release in June 2012.

Their fifth album, Hubardo, was released digitally on August 2013, with a vinyl release to follow.

Their sixth album, Coffins on Io, was released on October 15, 2014 through experimental metal label The Flenser. It is a concept album, and the first full-length album from Kayo Dot not to be self-released since 2010's Coyote.

Side projects include Tartar Lamb, Tartar Lamb II, and maudlin of the Well (to which Kayo Dot can be considered a spiritual successor, though the two projects now co-exist). Toby Driver's solo album In the L..L..Library Loft is also a Kayo Dot album in all but name, mainly being released under his name due to the record label's preference. Read more on Last.fm.
