Eriks got a rad voice. I think he only gets sharp and pitchy when he kinda gets timid and holds back. He could belt the fuck outta that song if he was 100% comfortable.
Kinda disappointed honestly, after hearing Erik's singing mic's Woowoo woo's, thought he'd do much better. He was off-key a lot, and couldn't hit the notes. Maybe he was a little intimidated or something?
