The same ideas are still propelling Corgan: Spirituality looms large on the 14-minute title track, and his eternal dedication to rock's redemptive might charges the giddy "Baby Let's Rock!," which Shania Twain obviously will never forgive him for writing first. But the bandleader sounds reinvigorated in a way he hasn't since Siamese Dream helped blow alt-rock wide open in 1993. No telling where Zwan will go in that amount of time, if it'll balloon to the same distended proportions the Pumpkins did; hopefully Corgan will pen another memo to himself to consult when that day comes. -- Mikael Wood
