Warner Music Australia-signing Gyroscope's third album "Breed Obsession" debuted at the top spot in this week's Motorola Australian Recording Industry Association (ARIA) chart.

The last Australian group to hit No. 1 on the ARIA album chart was Powderfinger, when its "Dream Days at the Hotel Existence" (Dew Process/Universal) opened at the peak on June 11, 2007.

Formed ten years ago in Perth, Gyroscope built up a sizable following through strong live performances, but has attracted minimal support from mainstream radio.

However the album's lead-off single "Snakeskin," from November 2007, reached No. 30 on the ARIA chart after being featured in free-to-air Network 10 promotions for the Australian Football League 2008 season.

The atmospheric guitar rock band peaked at No. 37 with its first album "Sound Shattering Sound" from June 2004, and at No. 20 with follow-up, "Are You Involved," released October 2005.

"Having a No. 1 debut allows us the chance to take the album back to (mainstream) radio," Warner Music Australia's Melbourne-based president of A&R Michael Parisi tells Billboard.biz.

He adds, "It also gives us a story to offer overseas record labels." The album was recorded in Liverpool U.K., and the video for "Snakeskin" was shot in the middle of a 200-metre crop circle near historic Stonehenge.

Warner Music set up the album with an intensive street level campaign and a national album "pre-Obsession" tour, which sold out. "We made sure we didn't alienate their fan base by giving them access priority with various initiatives," Parisi says.

One of these included an exclusive format of "Breed Obsession" with a bonus "making of" DVD sold through the electronics and CD/DVD retail chain JB Hi-Fi, which has an estimated 20% share of the recorded music retail market in Australia.

Gyroscope will embark on a stretch of eight club dates from May 2 to 18, with rising bands Young & Restless and Sugar Army.
