You know a singer or group of singers is good when you can't tell if it's a studio version or a live performance by hearing their voices. This is definately the case of the glee cast. You wouldn't tell it's a live performance if it wasn't for the crowd's shouting. It's a must for any glee fan. The only thing I'd say is not-so-good is precisely the crowd's voices, too loud sometimes and the fact that the songs are sang in the short TV versions instead of the full track as you could hear in the other CDs. Nevertheless, it's an amazing album, I can't wait to see the actual movie.
