Just what is a Whipstitch Sallie? WFYI asks three of the four female musicians  (Upright Bass Player Kat Erickson wasn’t able to join the group this day)  who perform Bluegrass Music under that name.  “Some of the songs are so old they are called traditional because no one even knows who wrote them but there are also people who are writing it now.”,  adds Allie Burbrink, who plays guitar, banjo, harmonica and founded the group with Sam in 2010. “ We’ve done a mix with traditional done in our own style and covering other peoples songs in our own style and trying to write our own based on things we like.”
