Holy Grail was born in Pasadena, California, in 2008 and hasn't slowed down for a second. They released their debut EP, Improper Burial, in 2009, followed by their 2010 critically acclaimed commercial smash Crisis In Utopia, which Metal Assault called "a mind-blowing effort that exudes unbounded freshness and musicianship."

Seattle-based musician Thom Beckman has released his instrumental solo heavy metal project, Shroud Of Spiders. Beckman plays all the lead parts on an electric mandolin — as well as the bass and drums. Beckman recently released a self-titled EP to launch this project, which you can hear in its entirety right here.

Some have tried playing the guitar with their teeth, behind their back, with their feet, etc. And then there was the inventive guitarist who, many decades ago, decided to slip a bottle over his finger and slide it along his guitar's strings (He probably emptied the bottle himself, if you know what I mean).

Fretboard Freedom is now available at the Guitar World Online Store.
