Once in a while an authentic and organic collaboration between artists and brands comes along. After introducing his first two music apps last year, Grammy-winning, iconic guitarist and Rock And Roll Hall Of Fame inductee Slash got a call from Rovio, the creator of the popular mobile game Angry Birds.

A longtime fan of the game since it debuted, Slash and Angry Birds Space have partnered to create the SlashBird character, a theme song performed by Slash and a ringtone.

Check out Slash's exclusive Q&A; with Mashable, regarding artists and music/tech partnerships, at this location.

“We're huge Slash fans, and Slash is a huge Angry Birds fan, so this was just an ideal match,” explains Philip Hickey Vice President, Marketing at Rovio. “It all happened very organically and was just a lot of fun on both sides. Our fans will love the track! Slash rocked the Angry Birds Space theme like only he could!"

Slash Featuring Myles Kennedy and The Conspirators are currently embarked on their world tour in support of their studio album, Apocalyptic Love. It spawned Slash two first-ever #1 rock radio hits with 'You’re A Lie' and 'Standing In The Sun'. Meanwhile, the album’s third single 'Anastasia”'is on track to break the Top 25 at Active Rock next week. The album was produced by Eric Valentine, who did the same honors for his first solo disc Slash, and all the songs on Apocalyptic Love were written together by Slash and Myles Kennedy.
