The Mudmen are a great band. The two big guys (brothers) that play the pipes are Rob and Sandy Campbell.
They were known on the competition pipe circuit as being a few of the best pipers in North America. They decided to take there act on the road with a slightly harder edge celtic rock band. If you get a chance to see them, go. You will not be disapointed. A lot of bands have one piper but they have two. You need a big sound to have 2 pipers. They have that and more.
Machummel knows the Campbell brothers. I think he made a few kilts for them last winter.
