[1] In 1998, Petr Hrdlička (vocals, guitar), Tomáš Kmec (bass), and František Vadlejch (drums) formed the thrash metal/punk band Skwar, with guitarist Leo Holan joining soon after.

[2] The same year, the band changed their name to ŠkWor (a play on the word "škvor", meaning "earworm" or "earwig"[1]) and released the album Vyhlašuju boj!, whose style was a departure from their debut and was compared to nu metal bands such as Linkin Park and Clawfinger.

In 2012, ŠkWor released their first official DVD, titled Natvrdo, which also included a bonus live CD and backstage footage.

In 2017, they announced the departure of longtime guitarist Leo Holan, who was subsequently replaced by Martin Volák (Debustrol, Harlej).
