For all the criticisms levied on head Pumpkin Billy Corgan, one thing he can't be accused of is being narrow in his artistic vision. On the breakthrough SIAMESE DREAM, he and co-producer Butch Vig built a landscape of layered, corrosive guitars that shimmered brighter with each additional glance. On MELLON COLLIE AND THE INFINITE SADNESS, Corgan turns his eye to the dreariness of modern existence and comes up with a broad alterna-rock opus that plays out like an offspring of Roger Waters and Kurt Cobain--verbose and angst-ridden, bleak in its view, cathartic in nature.
