Prosthetic Records seems to be leading this recent instru-metal movement with bands like Animals As Leaders and Scale The Summit. Now, they have added Felix Martin to their roster. Martin is a Venezuelan guitarist who uses a custom left-handed guitar with two adjacent 7-string necks. Shredgasm! You can see a preview clip of Martin’s upcoming Prosthetic debut, Live In Boston above, and then grab it when it hits stores on June 5th.
