### Instruction: Where was the heaviest A single filmed?
### Input: "Nothing" is the first single by English rock band A released from their album Hi-Fi Serious. It reached number nine in the UK Singles Chart; to date, A's highest charting single. During the promotion of the single, the band appeared on Top of The Pops and the Pepsi Chart Show.

The promotional video for Nothing was filmed in Cape Town, South Africa, mostly around the Artscape Theatre Centre formerly known as the Nico Malan theatre complex, and features extras dressed in the same clothes as each band member - complete with band member masks - to create the illusion that there are hundreds of duplicates of the band.

"Nothing" is arguably the heaviest A single, marking something of a departure from the band's usual melodic pop punk to nu metal. It is track 1 on the album Hi-Fi Serious. A live version appears on the live album, Rockin' Like Dokken.
### Response: A's first hit single Nothing was filmed in Cape Town, South Africa.
