definition i'm not happy with the definition as it stands and i would like to see a reference for the assertion that horslips were the first to name the genre celtic in modern usage means more than the ancient celts and much music that involves the lives of modern celts is considered celtic thus there's no reason a band like the pogues who sung frequently about irish matters should be considered less celtic simply because they were focused on the present similarly i see no reason horslips' driving hard rock is more suited towards being real celtic rock than the blues influenced music of l l era fairport
