Having gone through a number of lineup changes earlier in their career, the band currently consists of three Danes, guitarist/vocalist Asger Mygind, keyboardist Martin Werner and bassist Nicolai Mogensen; and one Swede, drummer Adam Janzi.

The band self-released their first EP, Homesick Machinery, in 2008,[1] which featured Mygind, guitarist Niels Dreijer, bassist Jeppe Bloch, Martin Werner on keyboards and Niklas Scherfig on drums.

[12] According to Mygind the lyrical themes on Inmazes relate to entrapment:[6] The album tries to capture this feeling of being trapped in mental mazes and not being able to fully experience happiness, basically.

How is this struggle visualized in your own mind and how do your surroundings react to the behaviour caused by it.On 2 June 2017, the band released their October Session EP, featuring new acoustic versions of two songs from Inmazes ("Gutter Moon" and "Stray the Skies"), with a video being produced for the latter.

[22] On 11 January 2019, the band released a lyric video for "Whaler" and were announced as the support act for Haken on their European tour throughout February and March.

[32] To promote Witness, the band performed a live-streamed concert from the swimming pool of the abandoned Auderød military camp in North Zealand, near Copenhagen, Denmark, on 11 September 2021.

[38] On their first album Inmazes, VOLA combined the typical sounds of progressive metal and electronic music, creating songs with odd time signatures, complex riffs and catchy and melodic choruses, with the cover banner drawing comparisons to Pink Floyd, Rammstein and Meshuggah.

[39][40] As explained by Mygind, even the name of the band (which was chosen by previous bassist Jeppe Bloch) reflects their sound in that they "try to do [their] choruses very majestic and grandios [sic]".

[42] Mygind is a big fan of British musician and producer Steven Wilson, choosing his top ten favourite songs for Prog magazine in November 2018.
