that song sounds sick. Tillians voice is high as FUCK haha. The music sounds exactly like DGD, stoked to hear it recorded.
Tilian's register is naturally higher than both Kurt and Jonny's. Tilian is an alto while Kurt and Jonny are both tenors. It's great in that he can hit any of their high notes with ease and go even higher, but he has to adjust their melodies for some of the lower notes when he does their songs live.
