Vocals is not something I mentioned in any of my learning objectives. The main reason for this was that I felt it would be too difficult to find a vocalist able to replicate the ways Muse’s Matt Bellamy or Rage Against the Machine’s Zac De La Rocha sing.
I did, however, take further inspiration from Rich Costey in the mixing stage of the vocals, in the form of adding distortion.

Costey mentions in the Sound on Sound article on ‘Absolution’ (linked below) that he recorded Matt Bellamy’s vocal parts by “clipping the mic pre — I’d deliberately clip the mic pre on ‘Time Is Running Out’ as he sang louder and louder, adding more intensity and grit to his vocal. Distorting a vocal is so commonplace nowadays that to me it’s the same as distorting a guitar or a bass. And much of the time when I’m mixing records for other people I’m distorting the vocal… whether they know it or not!”

While distorting the mic pre wasn’t really an option for me due to the system I recorded on, I did use the ‘clip distortion’ plug-in in Logic which I feel faithfully replicates the sound of distortion by means of clipping.

I added distortion to the majority of the vocals on my EP, not only because I took inspiration from the vocals on Absolution but also because I felt that it suited the style of music that I had written and my vocalist, Sam Carter.

I feel my project gains from distorted vocals as, to my ear, they blend more effectively with the guitars and the bass.
