You should really check out the "Heavy christmas", Raskasta joulua, wchich is a tour that happens every christmas in Finland - it is christmas songs made into style of heavy metal, it is amazing! :) You will know many of the songs they re doing. Many of these guys and many many more perform there. It is very popular in Finland.
E.g. Marko (one of those singers) used to be in Nightwish and he used to sing in band Tarot. Songs by Tarot times like "Tides", and especially their songs in "Heavy Metal on Ice " consert "Guardian Angel " and "Things that crawl at night" with Ice skaters are worth checking out 🤘😊👍: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8EsHGBW_uU8.htmlfeature=shared
