I love Rime. It has an amazing buildup, perhaps the single best one. The way it releases the tension when the solos kick in is nothing short of magical. What follows then are blinding solos.
But to me, what happens in Phantom is much more exciting. It is not 'only' the buildup and release of tension, but it is the construction and maintaining of a dramatic structure that consists of riffs, solos and harmonies that feed off each other and gets more tense and exciting, until the last segment virtually electrocutes you with its energy from the riff/solo/harmony combination. Yet the tension is not relieved before the vocals kick back in. There is so much more going on in this seemingly simple passage than in all of Rime.
