Math-rock

vialka.com Vialka hail from deepest France, via everywhere and nowhere. They are a devilishly high-spirited guitar/drums duo who tour hard and fast across the world. Their music skips joyfully across borders, channeling desert blues, Chinese folk songs, scatter rock and European gypsy song dynamics in a whirlwind of dervish energy. Their endless gypsy punk folk rock tales, hard hitting poly-rhythms and yelps and howls make for a danceable and intoxicating brew.

Hella began in 2001 in Sacramento, California as a two member band consisting of Zach Hill and Spencer Seim writing technically intricate music of a highly spastic nature. They play a blend of math rock and noise rock. On early albums, the band forged their classic sound, playing minimally arranged, abrasive instrumentals that still retain an idiosyncratic sense of melody. In 2005, the band expanded their live band by adding Dan Elkan on vocals, rhythm guitar, and synth and Jonathan Hischke on bass guitar.

Perth, Australia (2004 - present) Tangled Thoughts of Leaving emerged from the shadows of the live scene in Perth, Western Australia with the release of their 2008 EP, Tiny Fragments. By way of a piano-led amalgamation of prog, metal, post-rock, jazz, and nois - TToL have created a very unique sound. Members:
