Doesn't sound like too much compression to me. Depends on the music Genre and what is the desired result. if you have an inconsistent vocalist (dynamic wise) You very well may end up using a few stages of compression to "even" out their performance.
And Yes the right verb does allow the vocal to sit nicely in the mix. So it is up to you the mixer and the genre of music to determine how to approach making the vocal sit right.
Now as for me......
Over all, I will use a nice conservative amount of compression during tracking. IF, andf I repeat IF I have a nice compressor to do so.
2ndly, when mixing I get started and quickly get the lead vocal up so I am listening to it and it's relationship toeverything in the mix. Slowly building, eq'n compress'n, verbing, etc. whilst keeping in mind the relationship with this vocal and the track.
HOWEVER, IF..... IF the track dictates that the vocal is ancillary and for those doubters, some songs the vocal is Ancilliary to the song, then I approach the mix from a different perspective.
Example: Sometimes I'll start with Kick snare and hat, get them groovin' pretty nice, then add the lead. (dry, no eq), then i'll bring in the bass, get it grooving weith the drum and lead pretty nice then add a verb and some eq to the lead. See where I am at and move forward with the mix. Not all the time, but depending on what the song is saying that is one approach.
