Since Steve Vai's passion and Warfare, I have always been drawn to make an instrumental album. Following criterias had to be there, it can't be boring. Strong riffs with both straight and complex rhythms, virtouistic lead passages with nerve and melody, and great dynamics. There are over the top intense songs and very very relaxing songs with a lot of drama, You will love listening to this one with headphones as well as a hifi sound system. The album also had to sound great, and should be second to none.
