According to the band:
“It’s 11 tracks, because some of the tracks don’t have drums to begin with. It’s all the pop songs without drums… I think people will have a lot of fun with it because everyone keeps remixing ‘Birds of Paradise’ because there were no drums on it… I also mastered an instrumental version of the entire album. I always master multiple versions in case I want to collage or edit them later. I was really liking the way the vocal mixes sounded with no drums and I think that the drums on the album are so heavy, that it’s interesting to hear the record as this almost-empty, almost-a cappella kind of thing.”
