— Dale Martell of the Zebra Mussels band, a longtime group of experienced and seasoned musicians, says those are the qualities that has made the local group successful for so many years. The Mussels play at the Willow River Saloon on Saturday night, April 13. “We call it playing in the pocket,” getting into a groove and just going with the music, Martell said. Something that is a bit new for the band, for those who have not seen them for awhile, is that they now shift duties between three different lead singers. The Mussels play a lot of country, but also a range of other tunes.
