Australian electro-pop trio Sneaky Sound System's sophomore set "2" (Whack/MGM) has debuted at No. 1 on the Motorola Australian Recording Industry Assn. (ARIA) chart. It is the sixth domestic album to top the chart out of 17 chart toppers through 2008. The act's lead-off single "Kansas City" is at No. 16.

The set also debuted at No. 1 on the Australian Independent Recording Labels Assn. (AIR) chart. The act's self-titled 2007 debut album peaked at No. 5 on the ARIA chart and sold 200,000 units, according to Whack.

Sneaky Sound System promoted the release with a tie-in with mobile phone company Sony Ericsson's marketing of the latest Walkman phone. The firm tagged the album's release and accompanying tour (booked through New World Artists) in its television, print and street billboard advertising.

While the act has remained independent in its home market, it has signed a global deal with Warner Music U.K.'s imprint 14th Floor. Its debut single for the U.K. market, "Pictures", received radio airplay on top 40 stations BBC Radio 1 and Capital 95.8 and the band played at the Glastonbury Festival.

Sneaky Sound System's first album in the U.K. will be a hybrid of the two albums, according to manager Amber Zaga of Sydney-based Bacon Fat Mamma. A release date has not been firmed. Later this week, the trio will start touring through the U.K. and Europe until December, with dates booked through the William Morris Agency.

Zaga tells Billboard biz that the act will begin an assault on the North American market in the first half of 2009.
