Seven Lions releases a dark, bass heavy original, Serpent of Old. Jeff Montalvo, who is usually known for uplifting trance infused dubstep tracks, uses heavier bass synths with vocals by Ciscandra Nostalghia to provide an eerie backdrop that sets up for a big drop. Montalvo continues to provide some of the most qualified productions and with Serpent of Old, he proves this once again. This track is officially released today and can be purchased on iTunes.
