Normally when I hear the term “Supergroup,” I let out a disappointed sigh. Don’t get me wrong, it’s a great idea to have a bunch of your favorite musicians get together and collaborate on something new. The major problem with this however is that it often works better as an idea since the finished product never seems to live up to the hype. Other times, the supergroup offers nothing really new. Siege of Power is to defy that cliche.
