Dan Berggren, Peggy Lynn, and Dan Duggan have combined talents to create Jamcrackers, named in honor of the river drivers who broke up log jams. Those drivers worked hard to find solutions, to get things rolling again, and they couldn’t do the job alone. These three feel the same way about their music. With guitars and dulcimer (and other instruments), the trio showcases unique arrangements and striking harmonies as they present a diverse blend of folk and blues, ballads, gospel, and dance tunes.
