This is an amazing show from start to finish! These 6 brothers are all very talented and together are outstanding. They range from high tenor to low, low bass and even vocal percussion. Everything you hear is from their mouths, all acappella, but sounds like full instrumentation. My 16 year old son just loved it. They perform everything from Beach Boys, Coldplay, Justin Bieber (spoof), Wayne Newton, Tom Jones, Frank Sinatra, Kansas, and many more! A 2 hour show that is never a dull moment. I highly recommend this to everyone!!
