PAX. E3. Comic-Con. Gamescom. The Tokyo Game Show. What do all of those shows have in common? The smell.
Large numbers of humans packed together in a convention hall produces odours. That's just how it is. But, as this song points out, there is a way to mute that somewhat.
The song is by Savage Gypsy and it was created for this summer's A-Kon Anime convention.
