The 69th Pennsylvania Irish Volunteers was a regiment from Eastern Pennsylvania made up of Irish immigrants. The 69th Pennsylvania Irish Volunteers Band is a reenactment group that specializes in a combination of Irish songs and traditional civil war era music. Their latest cd, Rock of Erin, leans far more towards Irish music more than Civil War music. There is also more of a "pop" element to the tracks. If you are a fan of Irish music this is a nice cd, but if you are looking for more traditional Civil War music this is probably not what you want.
