[1] Neil Keener was (and in some cases, still is) involved with several punk rock and post-hardcore bands, including Planes Mistaken for Stars, Git Some, Red Cloud West, and Wovenhand.

Counts also gained notoriety in September 2006 when he created a mash-up of The Beach Boys' Pet Sounds with The Beatles' Sgt.

The band gained some acknowledgement in December 2009, when they released 118: The Chosen Priest and Apostle of Infinite Space, a piece that is over two months long.

Opium., something of an experimental hip-hop track; 289: CALCULOR, a calculator that doubles as a music generator; and 290: Two-Legged Tigers and Crocodiles, a sound collage piece.

In September they released a number of drone and post-rock tracks, and in November 299: Self-Traitor, I Do Bring the Spider Love, an hour-and-twenty-minute-long jazz fusion arrangement.

By the end of 2013, the band had uploaded most of their music to a public domain Internet Archive collection,[7] where all of their newer works reside as they continue to rebuild a new website.

On April 24, 2014, psychedelic rock band The Flaming Lips included a reference to Bull of Heaven in the liner notes of the vinyl release of the condensed version of their 24 hr.

[9][10] The Flaming Lips mistakenly call the band "Bull in Heaven," but refer to their pieces 118: The Chosen Priest and Apostle of Infinite Space and 210: Like a Wall in Which an Insect Lives and Gnaws specifically.

[11] In May 2016, Bull of Heaven were featured in a scholastic article entitled "Unperformable Works and the Ontology of Music" in the British Journal of Aesthetics, published by Oxford University Press.

[12][13][14] On December 4, 2016, Bull of Heaven made a post on their Facebook page announcing the death of member Clayton Counts.

[16] Neil has continued to make releases under the Bull of Heaven moniker, focusing on musical styles akin to progressive electronic and post-rock.

Bull of Heaven has only performed a handful of live shows, notably a party held by the Japanese band Boris in Denver in 2010,[17] and at the Lemp Neighborhood Arts Center in St. Louis in 2014.

In 2013, they put out the non-numbered Latin series, which consisted of drone/noise pieces mingled with numerous jam sessions with multiple musicians, notably which many were used and stitched together in the 83-minute psych rock track 299: Self-Traitor, I Do Bring The Spider Love..[20] In 2018, Keener resumed the Bull of Heaven project and abandoned the conventional numbered system.
