Envelope 24 for guitar quartet

Envelope 24 for guitar quartet  has been commissioned by KOA Guitar Quartet.

Envelope 24 is a diptych which holds a balance between classical music and heavy metal.
The first part is a processus in which every guitarist holds his own tempo.
As harmony gradually changes, accents are lifted out of the texture to form an ever evolving melody. In stark contrast to this soundscape, the second part brings a more aggressive statement.
In a first development, complex rhythmical patterns are combined with the use of power chords. This chaotic construction makes way for a rather odd sounding music box.
Slowly this pendulum-like module transforms and the piece swirls back in to chaos.
While rushing to the end, the opening theme gets stuck in a vortex and violently dissolves.

A recording of Envelope 24 is included in the debut album of Kales Guitar Quartet. Visit www.kalesguitarquartet.be for more information.
