Guitar legend YNGWIE MALMSTEEN is currently putting together his autobiography.

Touted as "the only real and true story written by Malmsteen himself," Relentless will be published in early 2013.

A trailer can be seen below.

As previously reported, the Swedish axe hero has launched his own instructional website, Relentless Shred.

Want to learn to play guitar - and actually impress? Dying to learn Yngwie's techniques? Tired of watching nobodies, trying to teach you how to play Yngwie's songs? Now, why would you take lessons from a random, when you can learn from Yngwie himself?
