With Tunnel Songs, Kecap Tuyul delivers his possibly darkest batch of half improvised ritual tunes to date on eg0cide productions. Prepared guitar is still at the core of his music, but voice and melodies are getting more in the foreground than before. The tracks of the album were loosely recorded between 2009 & 2014, and patiently mixed between 2012 & 2015 in various places.
