This week, SPIN celebrated its 25th anniversary with a week-long series of concerts in New York City, including memorable gigs from the Smashing Pumpkins, the National, the Flaming Lips, and the Black Keys.

The Smashing Pumpkins that kicked off their new tour at Cleveland's sweltering House of Blues Tuesday night aren't the same Smashing Pumpkins you know and love. But for parts of the 20-song, two-hour-plus show, it didn't matter.

Smashing Pumpkins just dropped the fifth song, "Freak," from their planned 44-track album Teargarden by Kaleidyscope, and it's a union of Billy Corgan's greatest traits: emotional pop-rock songwriting and heavy guitar heroics. Listen below!

Billy Corgan debuted his leaner, meaner Smashing Pumpkins on Wednesday night, roaring through a scintillating 80 minutes of songs old and new before ending the set nonplussed, a ukulele in his hand.
