Great harmonies and perfect blending, Blenders! They are very precise in how they start and end each note together; unified for sure. All the arrangements are first rate and feature great chords and lots of extras, too. They have so much sound that I am surprised to learn that there are only four guys in this group. They do a lot of flourishes in between the notes (doo, doot, doo; wooow; and so on), and they can sound like real instruments--horns that don't sound like someone pretending to be a horn. Another way that they are unified is that no one sticks out as being very different from the rest--like a basso profundo or a high tenor, not that this in itself is bad, but the togetherness works for them. Everything is fun and entertaining on this CD. Get this one if you would like a lighthearted a cappella group, or just if you want something to get your spirits up for the season.
