Serj Tankian's new solo EP, Elasticity, features songs originally conceived for another System Of A Down record, but have now been fully realized as a solo release. With his trademark eclecticism and one-of-a-kind vocal style, Serj delivers a collection that runs the gamut from hard-driving, electronically enhanced anthems like the title track, a rallying cry for his beloved Armenia (“Electric Yerevan”), the tongue-in-cheek political mash-up of “Your Mom,” the piano-laden “How Many Times?” and “Rumi,” a song that Serj wrote both about his son Rumi and Rumi the poet.
