Juan Martin "jg6" is a guitarist from Barcelona (Spain) and plays in Bartok one of the most active progressive metal band in his country. He starts to play guitar at the age of 15 years old and even now continues to refine his guitar techniques, among his influences: Yngwie Malmsteen, Paul Gilbert, Steve Vai, John Petrucci and Mattias “IA” Eklundh just to name a few.

In 2006 appears his first instrumental album called "Flying Reindeer" six own songs and two crazy versions “The Entertainer” Scott Joplin and “Winter” a extract from Vivaldi’s Four seasons. This album "Guitar Farm" is inspired by some animal sounds to create effects on the electric guitar. Melodic, aggressive, generous with time changes and new point of view in such guitar-instrumental music.
