ASHLAND Even though an Ashland band serendipitously got involved with a Veterans Day event, it was a perfect fit. Four Skulls, a rock band based in Ashland, will perform Friday at the Blue Parrot at 14 Capitol St. in Charleston in a lineup that includes West Virginia band Wolves of the Calla and Delaware group Violence in Ascension. The show will benefit Guitars for Vets, a charity that provides donated guitars and free lessons to veterans recovering from Post-Traumatic Stres
