30 Days of Bass and Video

30 days of Bass and Video was recorded and composed over 30 days. The album explores the sonic palette of the electric bass guitar and how the art of film could affect the way you compose.  All the compositon are based on sounds or film and are purely performed on the electric bass guitar.

Every day a new video with new music was upload to Youtube, during this production. Feel free to check it out on my YouTube channel


The songbook Emerald is a compilation of 50 compositions written during the timespan of three weeks, during the summer of 2018. 

Inspired by the Masada book by John Zorn, Mielonen wanted to explore how deadlines and limitations compositionally could push you to explore new areas of yourself. 

The written music is now a intergral part of Sisucunda's repetoire.
