Hey, that's pretty darn good!
I'll have to admit, that I've never listened to or heard Coldplay, although I believe I've heard the name. I don't know if they're an 80's or 90's band, or anything else whatsoever about them or their music.
I think the production value and playing on this recording is very strong. The weak points might still be the falsetto. I give you props for doing it, though.
I try to avoid breaking into falsetto, as much as possible. No doubt, some songs demand it, or feature falsetto in some way, like maybe this one.
Instead of doing falsetto myself, I might try to find a girlfriend or female singer who could do the high parts. When having done this, it yielded a much more pleasing vocal with the female voice doing all the highs. Alternately, if a vocal's too high, but not necessarily in falsetto, & I have no female vocalist handy,... I'll try almost any other solution, than to break into falsetto. I've never done it well, and have not really liked the results that well, when I have committed it to tape.
I can tell that this song is based in a high vocal part in those in-between spots, so it's okay if the song absolutely demands falsetto, in one way or another.
Overall, the song's very well put together, played well, hifi audio recording & a really good job. Nice fade & everything.
So, is Layne Staley a famous name? If not, then it should be. It just sounds famous.
