Australian alternative rock outfit Gyroscope has fired a broadside at their former label Warner Music for readying a hits compilation apparently without their consent.

In a statement issued today (April 22) and posted on their official Web site, the members of Gyroscope wrote, "It has just come to our attention that Warner Music are releasing a 'Best of Gyroscope' album. We only found out about this release after being notified by our fans on Facebook."

According to the group - which comprises frontman Dan Sanders, guitarist Zoran Trivic, bassist Brad Campbell and drummer Rob Nassif -- the hits set's "song selection, artwork and everything about this release has been done without consultation with the band."

Warner Music has yet to publicly announce plans for a Gyroscope best-of, and the music major did not respond.

However, has seen a graphic of the planned compilation. The 15-song album, entitled "The Best of Gyroscope," has an expected April 30 release date.

Now signed to Island Records, Gyroscope's fourth studio album "Cohesion" debuted at No. 3 on the ARIA albums chart last Sunday (April 18).

"Cohesion" is the follow up to the Warner Music Australia release "Breed Obsession," which topped the chart for a week on its release in March 2008.

The band will support the "Cohesion" with a national tour beginning June 4 at the Prince Of Wales venue in Bunbury in the band's native Western Australia.
