I'm always impressed when I see any cover online featuring the music from Banjo Kazooie! The music is so intricate and well-done that you have to be pretty good to do it justice. I think these guys killed this cover of "Grunthilda's Lair". Sure the video has no thrills, but you're here for the music so click the video and look at something else while you listen if you don't want to see two dudes on a couch playing guitar. It's worth your time I promise.
