Haken was formed by school friends
Ross Jennings (vocals), Matthew Marshall (guitar), and Henshall at first in 2004. The members parted ways for a while to study at university, reuniting in 2007. The current members hired Peter Jones on keyboards and Raymond Hearne on drums. Jones left soon after, and was replaced by Diego Tejeida. Charlie Griffiths was found on guitar, and Henshall brought in To-Mera bandmate Tom Maclean on bass. Henshall has composed most of Haken's songs by himself and contributed to some of the lyrics. He composed the whole
Aquarius album alone, most of
Visions (except "Premonition", co-written with
keyboardist Diego Tejeida and bassist Thomas MacLean; and "Insomnia", written by all members), and most of
The Mountain (except "As Death Embraces", written by Tejeida). In this album, Henshall (as well as every other instrumentalist in the band) contributed with lyrics for the first time, on the song "Cockroach King". He would be credited as a lyricist again in the band's 2014 EP
Restoration, for the song "Crystallised" (co-written with Hearne and Griffiths).
Affinity (2016) and
Vector (2018) both credited all songwriting to every band member. ==Opinaut==
