The band consists of former the Mars Volta members Omar Rodríguez-López (guitar, backing vocals) and Deantoni Parks (drums, keyboards), alongside Le Butcherettes vocalist Teri Gender Bender and Nicci Kasper of KUDU and We Are Dark Angels (keyboards).

Initially billed as a variation on the Omar Rodriguez Lopez Group, the band was formed following a decision to put Rodriguez-Lopez's primary project, The Mars Volta, on hiatus.

[1] In March 2012, The Mars Volta released its sixth studio album, Noctourniquet, following a lengthy three year recording period.

Following the tour's completion, Rodríguez-López moved back to his home town of El Paso, Texas, and subsequently formed Bosnian Rainbows with frequent collaborator Teri Gender Bender of Le Butcherettes, Mars Volta drummer Deantoni Parks and Nicci Kasper, who previously worked with Parks in Kudu and also as the writing duo Dark Angels.

So it got booked one way, but I try to make it clear every night that this is a new group, and these are the names of the players, and “thank you.”"[3] The band chose to rehearse in Hamburg at Clouds Hill Studios, owned by Rodriguez-Lopez's longtime friend Johann Scheerer.

After the European leg of the tour they returned to the studio to record their self-titled debut album, with production by Scheerer.

[11] However the band went inactive in 2014, as Rodriguez-Lopez reunited with his Mars Volta partner Cedric Bixler-Zavala in a new project Antemasque.
