From W20 Kinfolk: A Breed Apart, pg 30, under Widdershins Society:
Twenty years ago, Fianna Kinfolk Padraig and Aidan Conneely formed Widdershins, a Celtic folk band made up of their musically talented friends, all from Fianna stock. [...] Other Celtic folk groups have since joined the Widdershins Society: Wolves of the Highlands, specializing in Scottish folk songs and featuring bagpipes and Scottish pipe and drums, makes their way up
and down the Appalachian region; Gaelsong, an acapella group of Kinfolk, regularly tour the arts and crafts fairs and anywhere else that invites them; Taliesin’s Songbird, a Welsh folk band with connections on both sides of the Atlantic; and there are others. [...] While the Widdershins Society remains a Fianna society, other tribes have followed suit, and some have formed their own Kinfolk musical societies. Pan and the Muse, a duo made up of a pair of Black Fury fraternal twins, Andromache and
Andros Peloppaneus, bring ancient Greek songs into the modern age and anchor a group of Black Fury male and female Kinfolk; Gertie’s Jug Band centers around a large network of Bone Gnawer Kin, providing Cajun and Zydeco music as well as soup kitchens to feed and entertain homeless populations; Potlatch Songs consists of young Wendigo Kinfolk musicians eager to bring a strong environmental and natural living message to the world, believing that this
can help strengthen Gaia for the coming battle. Each tribe has at least one musical Kinfolk group providing musical and social connections.
That's all I got about Garou/Kinfolk bands. Does this help?
