Slough Feg (a band I had only listened to once before) were awesome; a traditional metal band fronted by a vocalist/guitarist with a great voice and a lot of sass, I was very impressed by what I saw. Most of their set comprised of Lord Weird Slough Feg covers (the former incantation of the band)
Same band, man. They just shortened their name. They weren't really covering songs, they're their own just under a different name.
