Interesting! I *love* REO, and I've seen then more than any other band at this point (4x). Some really don't care for Kevin's vocal mannerisms and haven't from the beginning.
And to the best of my recollection, it's been probably 2/2.5 years since I've seen the guys last - Kevin wasn't using vocal tracks or lip syncing. It was painfully obvious on Keep On Lovin' You and Take It On The Run as I remember. On those high notes it was cracking and very frail sounding. Other lines he would "whisper sing" to try to hit those notes. And hey, I'm not complaining - aging is an inevitable process that sadly affects some more than others. At least Kevin Cronin could sing well at one point, unlike Don Felder.
I need to see them again though! They always put on a good show and I like all of their music from the earliest more hard rock numbers right up through the power ballad era. Then again, maybe I won't enjoy myself as much if he's lip syncing the whole time. I guess I'd rather have the realness warts and all from a singer like Kevin. Felder, eh...
