All the instruments, melodies and arrangements have been 100% made by the producer. No free-royalty use loops have been used to create any part of the instrumental of this track. There can only be loops only in the drums section (claps, shakers, top loops, etc) and ambient or vocal samples as a support of the production arrangement.
Process note
I wrote this dark cello melody and added bells and Piano to increase the darkness. Then i added some heavy punchy drums to make this beat more dark and agressive.
