Sorry for the late post on this! It's a performance of "Living After Midnight" by Judas Priest and Steel Panther from November 22. The performance took place in Tacoma, Washington, during the bands' joint tour.
Below, check out some fan-filmed footage of Metallica's Kirk Hammett performing Judas Priest's "Grinder" and Metallica's "Seek & Destroy" with Exodus and Mark Osegueda of Death Angel. Note that Metallica bassist Robert Trujillo joins the band for "Seek & Destroy."
Here's an ode to a piece of gadgetry rarely covered on GuitarWorld.com, something that has brought a whole new world of sounds to guitarists' fingertips: the guitar synthesizer, aka the guitar synth. First of all, exactly what is a guitar synth? To quote Norm Leet, who wrote an authoratative feature on the topic for Roland's UK website, "a guitar synth is a synth module whose input device is a guitar instead of a keyboard."
Today, the guys in Judas Priest are previewing another new song from their upcoming studio album, Redeemer of Souls. Check out the under-two-minute teaser for "Battle Cry" below! The clip also features an intro and commentary by Judas Priest guitarist Richie Faulkner.
