Bison BC - Feature

Bison B.C. – Symmetry B.C.

19th of February, 2012

Bison B.C. is a Canadian Sludge Metal band from Vancouver. Their second (third, if you count their 2007 EP/LP Earthbound) full length album was released in 2010 through Metal Blade Records. Honestly, this record might be my most-listened to album since 2010. I’m actually not the biggest Sludge fan (I’m more a Death Metal guy), but this record and their live performance in Hamburg’s Hafenklang in that year gave me an instant erection that’s just not ebbing away. Just listen to Stressed Elephant, the opener of the release and you’ll know what I mean.

Kylesa – Distance closing in

28th of January, 2012

Kylesa is a Sludge Metal / Psychedelic Rock band from Savannah, Georgia, and was founded in 2001. To this day they have released five studio albums with Spiral Shadow being the last one, released in 2010.

The cover for this brilliant release (one of my 2010 Top 10 albums) was done by the artist Santos and shows the endless spiral of a tree (being continued in the booklet) containing a special kind of symmetry: The helical symmetry. The most common examples of helical symmetries are drill bits or springs.

“It can be thought of as rotational symmetry along with translation along the axis of rotation, the screw axis. It can be visualized as the tracing in three-dimensional space that results from rotating an object at an even angular speed while simultaneously moving at another even speed along its axis of rotation.” (source)
