Atum has songs to fit nearly every SP era, while also going some new directions. This listener since '93 is very happy. Atum has the best musical cohesion of any SP effort since Melloncollie and the Infinate Sadness. Atum will grow on you. I find myself getting into songs I brushed off after first listen. Give it a few listens in its entirety.
Finally nevermind those elitist nitwits from Netphoria claiming Atum isn't SP. They've been bashing everything SP/Billy Corgan has done for the last 25 years. I guess one must have a hobby. Sooner or later they will grow up and move on or perish in their disillusionment.
