Jon Wesseltoft and Lasse Marhaug started Tongues Of Mount Meru in 2008 as a way to explore their mutual interest in long-form music, psycho-acoustics, and the phenomenology of sound, and its correlation to perception. Their work as Tongues Of Mount Meru is characterised by a stringent and multilayered flow of sound information, with an almost hypnotic quality. This is music that at times is clean-cut and saw buzzing, and at times lucidly beautiful, but always in demand of the listener's full attention. This music was recorded in 2013 and consists of two pieces that reflect into each other. Both stringent and close-knitted with microtonal frequency interaction, with a slowly unsettling shifting movement. Both pieces gradually blooming within its own sonic time-space, to reveal microscopic movements in tonality, binaural beat patterns and ghostly strata of overtones.
