i"m sorry i just really dislike Chris's voice...

I do have to agree that Rachel/Lea does have an amazing powerhouse of a voice. She is extremely talented and has one of the most clear, amazing voices I've heard.
However, I think Kurt/Chris's voice is fantastic and wonderful. Of course his voice is high...but that doesn't mean anything. I wish he had more vocal parts in the series. His voice beautiful and lovely and makes me smile.
So in the battle between Rachel and Kurt, they both are amazing, and Rachel's voice is better suited for it, but Kurt does have a lovely voice that deserves more performance time.
It may be a bit over-produced, but how can you tell that they are lip syncing? Honestly I can't tell.

i just love it when Lea Michele sings so she wins hands down.

Rachel not doubt.

Nice effort by Kurt/Chris but really not the song to showcase her voice. Plus Lea Michele is a powerhouse with a truly amazing voice.

Kurt's voice was just way too high / feminine. It didn't really have the range that Rachel had...

I don't know of any TV or film musical that's actually sung live.

I agree it is slightly on the side of being a bit over-produced and could be better melded in. But I suspect it has a lot to do with it being a TV series and that they are doing this week after week with a much shorter time constraint then say a movie like Chicago that have a lot more time to make the music blend with the show.

However it is getting better and better melded. I suspect that it'll take about 1 season to lock down a good blend for the production to use that will be workable in a quick turnaround format, but at the same time not feel so out of place. I definitely thought this week's episode was much less out of place then previous weeks. I recall wheneven Will sung, the whole thing was so completely over the top over produced where his voice was definitely enhanced. I think if they just tone down enhancing the voices to some sort of Pop-CD quality, the show would be more believable.

Lea Michele's voice is very Broadway. She played Wendla in Spring Awakening. Her voice is beyond amazing.

All the songs on Glee are just to overproduced. I never felt that the actors are singing on spot, it is almost just a lipsync act. The producers should look more at HighSchoolMusical, I haven't seen this problem there.

Another thing that bothers me, at a moment in this clip you see a trumpetplayer and a tromboneplayer blowing their lungs out, but still you can't hear them. And the trumpetsound you hear is from a synthesizer.
Why not let the musicians and singers do it 'live' and enhance the sound. And not put a whole new soundtrack under it.

Doesn't Lea Michele remind you of Idina Menzel?

this episode was much better than some of the others so far this season, and I think it's because it focused on the kids and not Will's love life. I liked getting to know Arty better, and thought he had a smoothness to his voice I wasn't expecting. I also really like how they're handling Kurt and his Dad's relationship, I really think it will open doors for kids and parents around the country.
