Billy Corgan Collapses During Smashing Pumpkins Concert

'That wasn't a stage move or clumsiness— that was me blacking out,' Corgan tweeted after Tampa, Florida, show.

If Billy Corgan falls on a stage in South Florida, and no one notices, does he make a sound?

It's an existential question, to be sure, but a valid one. Especially after what took place during a Smashing Pumpkins' concert on Wednesday (July 21) night in Tampa, Florida, when Corgan collapsed on stage while performing "Bullet With Butterfly Wings" and seemingly no one — at least not anyone reviewing the show — seemed to notice.

In fact, it wasn't until the following morning, when Corgan took to his Twitter account to address the incident, that anyone began reporting on his spill, which he attributed to "blacking out."

"Thanks a million to the fans in Tampa last night for a tremendous show! We can't tell you how much we appreciate you today," he wrote. "And for those that saw me fall last night during 'Bullet,' that wasn't a stage move or clumsiness — that was me blacking out and wiping out.

"I have no memory of falling against the drum riser and my guitar cabinet," Corgan continued. "But I can tell you I've got quite a good bruise and am moving slow."

In YouTube footage posted after the show, Corgan can be seen leading the sold-out crowd in a sing-along of the iconic "Bullet" chorus. Then, after taking a step back from his mic stand, the SP frontman collapses on the floor. Most in the audience didn't notice the spill, and he was back on his feet within seconds.

Aside from some bruising, Corgan appeared to have suffered no other injuries after the collapse, as he spent the rest of Thursday taking meetings with folks at TNA Wrestling in Nashville .
