This track was composed using a Sherman Filterbank and delay pedals. The more buzzy sounds are from the Sherman. This is another drone piece, with microtonals, a wall of sound with harmonics clearly amplified and the Sherman augmenting the shimmeryness of the sound.
Especially at the beginning (0.00 – 1.50) of this track there is a sense of pleading… moving on to a new low frequency note… a new mid frequency note … towards the end the drone becomes more settled and the Sherman frequencies come to the fore..
