On Alice in Chains' 1992 track God Smack, Layne Staley's vocal tremolos seem pretty far-fetched to me. I'm guessing the effect was applied in the studio during the recording process. Nonetheless, I'm curious to know if it's possible to replicate such vocals live, and if so, how?
Here is one live performance, at which Layne certainly doesn't seem to be able to do so. Perhaps it would be easier for someone trained in a different style? If so, what techniques would be involved?
Thanks in advance!
