Devour the Day have joined forces with guitar great Gus G. on the title track to the latter's upcoming new album, 'I Am the Fire.' And now DTD are telling the story of how the collaboration came together.

The band admits they were not expecting to hear from Ozzy Osbourne's guitarist as he was putting together his new disc. In a new Facebook posting, Devour the Day detail exactly how they came to appear on the new Gus G. album.

Guitarist Joey "Chicago" Walser says, "A few months back we caught wind that Gus G. (Ozzy Osbourne's lead guitar player) was doing a solo record (YES!!!). He was 99 percent of the way done, but he felt like there was a track missing. We later discovered he had listened to many bands current songs and Blake [Allison]'s voice and attitude (and devilish good looks) really stood out to him. His people called our people and a few weeks later Blake and I received an instrumental track called '13.'"

The guitarist continues, "We had a mission ... to write melody and lyric for a new Gus G. track! Pressure! We started to throw around ideas. As the song lyrics started to take shape we really wanted to change the perspective of the voice. Who was singing this song? We wanted it to be from the point of view of passion itself. What would determination say if it could talk? If the fire that burns inside you could give you advice, what would it say? We were on to something."

Walser says the band flew to Los Angeles to share their idea and the guitarist loved it. "We immediately started work on tracking the vocal. Then Gus came in and recorded a solo that bent the very fabric of time and space, no biggie."

The guitarist concludes, "'I Am the Fire' is meant to be inspirational. We want the listener to feel empowered as they conquer their next challenge. It has awesome guitar work, killer tones and a great mix of Gus G. and Devour the Day, like a super futuristic rock Voltron."

Fans can pick up the new Gus G. and Devour the Day single 'I Am the Fire' via iTunes. The album, which is due March 18, is also available at this location. And Devour the Day fans can also purchase the band's debut disc, 'Time and Pressure,' here.
