Tinged with just enough of glam's sense of dramatic gloominess, consider the descending chords of the riff, however rejigged from the simpler three-downward-note formula familiar to Marc Bolan -- with "Today," the Smashing Pumpkins broke into the big time with an at-once storming but catchy smash single. The fact that Billy Corgan's words were based on a day when he was feeling near-suicidal, the irony of the almost softly sighed lyrics throughout becomes patently obvious: "Today is the greatest day I've ever known/Can't wait for tomorrow." It's a sly joke but also not an apparent one, and most were content to take it on face value. No surprise given how rich and enveloping the music was -- Corgan, as with everything on Siamese Dream, recording all parts but Jimmy Chamberlin's drums himself, started with a soft opening chime before pouring on the majestic feedback blasts. "Today" alternates between calmer, almost Cure-like sections and the louder crunches, his soon-to-be-trademark guitar style taking My Bloody Valentine's own hypnotic riffing to more accessible results.
