Collin McLoughlin & Skrux, two quickly emerging names in the EDM scene, have been putting up impressive Dubstep tracks for the past few years, and this remix doesn’t fall short. They collaborated and remixed T.I.‘s “Castle Walls,” which features Christina Aguilera. The remix is a synth-heavy, melancholy, yet uplifting take on the hip-hop based original. A soaring pluck travels through the track, guiding the listener from heavy bass and classic saw pads, to crunchy drums and vocal shots, making this a perfect mix between subtle beauty and hard-hitting bass. All the elements of the track come together beautifully with Aguilera’s powerful vocals, and even though they excluded T.I.’s rap verse, this remix makes for an intriguing way to kick off 2014 for both artists.
