Just another wild hair. I d/l a backing track, sang all the vocal parts.
For the inquisitive.... the vid is me singing TO the prev vocals I did. (ie, not live). I tried to sing it so that it LOOKS live because I did record it that way but then later realized I had made a lyric mistake and some things I wanted to redo.
I pitched the track DOWN by 6 semitones. Sang it all. Pitched the track back up to normal THEN pitched all my vocal tracks up by 6. I used a buttload of eq and some auto-tune and compression and multiband compression and delay AND reverb AND doubling of the lead vocal after each first half of the verses.
