First coined by the Swedish Progressive Metal
band Vildhjarta, the meaning of thall was kept very secret for years, and was used as an inside joke to torment members of the djent community. Some speculated it was the name of their debut
LP release, but this proved to be incorrect as Vildhjarta put out an album named Masstaden instead. Others speculated it was onomatopoeic, in the same manner as the word "djent"; used to describe the twangy thall
sound of Vildhjarta'
s heavily-distorted extended range guitars. This proved also to be inaccurate.
The origins of the word thall were revealed by Calle and Daniel - they were slurring the word Thrull, and after, took it upon themselves to share the hilarious distortion of the word all over the
internet. The word's popularity was hugely propagated by their rabid fanbase who would embrace thall and frequently leave comments consisting of just the word alone all over
facebook and
youtube.
Thus, thall has no true meaning, but has become a word unto itself.
