Oh, I see what you mean. I thought you were in the same
venue at the same setup for some reason.
Ok, I listened to that clip. I don't know which one you are but the opening guy sounds fine.
Maybe the level's a little low, but there's a sort of hed pe thing going on. Works fine to me.
The second guy (1:28) sounds ok too. That recording's a little fuller but I think it works ok.
The only thing that takes me ear is when the two voices are together it sounds a little messy.
I think I'd be playing with the panning though and not much more.
That should help to separate the voices.
At a push I might HPF the second voice when both voices are together.
IDK, maybe the low end in the second voice is the difference you're hearing?
Something like that wouldn't necessarily stand out when solod, but it can certainly ruin how a voice sits in a mix.
Maybe it's
the other way round and you're the first guy? (Since you said metallic)
If so
you might wanna hear more low end to match the other guy.
Personally, I think it works as is.
Maybe someone else will add comments.
