Formed in October 2014, North Carolina's Extinction Level Event (ELE). Their all bassist lineup, are already taking the Metal world by storm. The brain child of bassist Duncan Pardue and guitarist-turned-bassist Ryan Reedy, ELE's unique lineup born out of necessity. Unable to create the low, Meshuggah-esque sound that Ryan desired with the standard guitar/bass setup, the decision was made to forgo the guitars all together.
These are videos from concerts where Extinction Level Event played, so they may be of other bands that played the concert as well.
