I saw these guys play in Buffalo, NY right by the water and it started to rain so hard that they had to stop playing for awhile. When it stopped raining they started playing again and a double rainbow came through the clouds over the river. It was so serendipitous :)
Not generally a fan of cover bands either. But I saw DSO years ago at a festival and was pretty impressed. I probably would never buy a ticket just to see them but they are definitely worth checking out at a festival or something.
