The Pulse of Radio reports: DISTURBED's new single, "Inside The Fire", made a huge impact at rock radio during the past week, with the song officially added to the playlists of more than 60 stations. The track is taken from the band's upcoming new album, "Indestructible", and singer David Draiman says it's one of the darkest songs he's ever written. "It is based on a true story of my own where, when I was about 16 or so, I had a girlfriend of mine commit suicide," he said. "It was an unbelievably horrific and painful experience, and it was cathartic to make the song, and it really took me having a certain mindset to do it, and I had to wait 'til I was ready."DISTURBED has set June 3 as the release date for "Indestructible". Another new song from the album, called "Perfect Insanity", is now available at the band's official web site, Disturbed1.com. The Chicago-based band will begin a spring U.S. tour on April 26 in Little Rock, Arkansas, with dates stretching into late May. Following its spring solo run and European dates in June, DISTURBED will co-headline the Rockstar Mayhem Energy Tour with SLIPKNOT in July and August.
