Metalcore is an ever-evolving genre, but In Shallows is proving to keep up with their new single, "Undertaker."This track will load you with enough energy to put your frustration to the pit. Bitter, stabbing lyrics of betrayal pair perfectly with the loud, punchy backtrack. The lyrics outwardly display an internal battle, debating whether to hold onto the past or to grow despite it. It articulates how anger can be infectious not only to others but to yourself. Delivery of different lines build into this as well, transitioning from melodic singing to intense growls. The complexity of the instrumentation emphasizes the message. Everything from rapid riffs to pitch harmonics come together to create a powerfully chaotic feeling. Like many metalcore classics, this song shines with an impeccable bridge. It offers a strong build-up just to slow down before the final chorus finishes the track strongly. Every layer of the song fits together seamlessly; all the more impressive as it was composed with two new band members. Overall, "Undertaker" is a track that will have heads banging and crowds jumping.  As the scene grows, In Shallows will undoubtedly be crucial in the new metalcore era. Keep up with In Shallows and their future releases here.
