Query: Josh Groban, "Live at the Greek"

I'm very confused as to how they made and released this DVD set. There are so many flaws in Josh Groban's singing, and yes, I can clearly hear the problems with his voice. I don't really care why he sounds so bad, I do care that I wasted my money on this really bad sounding concert. The fans deserve better.From the getgo, I heard Groban singing with a warble and then he graduated to very nasal. Gee, I don't have to be a vocal genius to tell this is a problem.I think Josh Groban has many great performances in his future. Unfortunately, this wasn't one of them.If you haven't bought this one yet, take caution. Listen first. Hey! If you love it, then you haven't wasted your bucks.
