There are about 378 guitars overdubbed on this song. The wall of distortion is impenetrable. It is such a satisfying sound. Luckily, or likely by design, Billy Corgan's high, whispy voice is able to stand apart from all the low-end swirl.
There is nothing I like more than a heavy, guitar-laden song that manages to retain an intelligent major key. There is something so defiant about it, the ability to hit hard but with attention to the thirds. So many groups just toss them out and power it with the fifths, just getting by on those roots instead of having to manage actual harmony.
Billy Corgan was such an underrated guitar soloist as well, somebody capable of doing all the Van Halen things but warping his playing into a squealing blast belying his sound fundamentals.
I have read someone calling Smashing Pumpkins the REO Speedwagon of grunge bands. That seems to indicate some lack of integrity. I'm not going to speak for their entire career arc, or to the petulant drama all the band members engaged in, but for at least this album, things were controlled, ambitious, and jubilant. They at least forced integrity, with the weight of 378 major chords.
