I know what you mean about the genres .. I'm most into hard rock, prog rock and metal, but I prefer to keep it at that and not get too specific.
By the way, this might seem a little weird, but since you're from north Wales .. I' from Norway and I plan on vacating to Wales/England with some friends this summer. We want to go on a boat rental trip on the Llangollen canal. However, I've been a little uncertain about the weather .. Do you know if it's usually nice there around the first week in august?
