On Tuesday, Smashing Pumpkins are releasing If All Goes Wrong, a DVD documentary that follows their reformation last year, on which this unreleased, acoustic track, “99 Floors,” is featured. The performance was filmed during the band’s residency in San Francisco, and finds Billy Corgan playing the troubled troubadour role in the middle of the rest of the band who don’t have much to do until near the end of the somber song.
