Oli is so weak live, I watched the set they did at Reading and I agree he just lets the rest of the band down. His vocals were pretty terrible live when I saw them with Parkway too.
Probably enhanced a hell of a lot. Cause he's straight up garbage live, but (puts on flame shield) I like his studio vocals.Makes me wonder how much of his vocals on the records is enhanced. Guessing that Count Your Blessings just wrecked his vocal chords as well as doing the vocals in a bad way when live.
