[1] After the disbandment of the industrial metal band Omega Lithium, two of its members, Marko Matijević Sekul and Zoltan Lečei, went on to form Manntra.,[2] immediately calling Andrea Kert as a drummer.

The band often employs traditional instruments such as the sopele, the tamburica and the diple, alongside electric guitars, drums, and keyboards.

Their music is notable for its dynamic rhythms, driving guitar riffs, and powerful vocals, often delivered in both Croatian and English.

The band's lyrics frequently deal with themes of spirituality, mythology, and personal struggle, which are often drawn from Croatian folklore and history.

Venera, released in 2015, showcased the band's evolving sound, incorporating less electronic elements and more raw folk instruments.

The album featured a more ambitious and experimental approach which aimed closer to home, showcasing Balkan's soundscape, but finding some success outside Croatia, as well.

[14] Kreatura expanded on Manntra's interest in regional folklore and mythical stories and returned slightly to a metal and industrial sound.
