SLO FEST is headlined by Itchy McGuirk who began its legacy firmly rooted in the central coast music scene in the early 90’s. After recording three albums, and enjoying noteworthy success in the music world, the band separated in the late 90’s. In 2010, the surviving members of the band reunited for a special memorial concert to honor founding member, Mark Kafoury after he unexpectedly passed away early that year. Since then, the band has been reuniting annually to celebrate Mark and raise money for fellow Cal Poly alumni and their families affected by serious illness through an organization called SLO Fest. Itchy McGuirk is made up of Doug Groshart- lead vocals and keys, Helen Tracewell Guzzi- vocals, Jon Scholl- bass guitar, Dave Walker- drums, and Dan Ernst- guitar.
