Three of the leading gear/technology companies for both musicians and consumers alike - Hartke, Samson, and Zoom - are returning with their successful Metal Masters clinic series. Partnering up with Guitar Center, Metal Masters 4 will take place in New York City on September 7th at The Gramercy. Doors will open at 7pm, with the clinic starting at 8pm.

DOWN vocalist Phil Anselmo, formerly of PANTERA and SUPERJOINT RITUAL, has filmed the following video update in advance of tomorrow's clinic:

Metal Masters 4 is bringing back some of the classic “Metal Masters” while adding a few new members to the list. As always, fans can expect some surprise appearances and unforgettable performances. Metal Masters 4 will be comprised of Philip Anselmo (Down, ex-PANTERA), Kerry King and Dave Lombardo (SLAYER), Scott Ian, Charlie Benante, and Frank Bello (ANTHRAX) and newly added masters Billy Sheehan (MR. BIG, DLR) and Gary Holt (EXODUS, Slayer).

If the still-circulating buzz from Metal Masters 3 is any indication, Metal Masters 4 will not disappoint anyone who is lucky enough to see it. Metal Masters 3, which took place at the Key Club in Los Angeles, featured the “Metal Masters” demonstrating their personal techniques and styles used to create the music that millions bang their heads to every day. The highlight of the event came when vocalist and now returning “Metal Master” Philip Anselmo jumped onstage to perform Slayer fan-favorites 'Angel Of Death' and 'Raining Blood' before launching into five songs from the Pantera classic album, Vulgar Display Of Power. Anselmo and the “Metal Masters” comprised of David Ellefson (MEGADETH), Chris Broderick (Megadeth), Kerry King (Slayer), Dave Lombardo (Slayer), Charlie Benante (Anthrax), Frank Bello (Anthrax) and Mike Portnoy (ADRENALINE MOB, FLYING COLORS), blazed through 'Mouth For War', 'A New Level', 'Walk', 'Fucking Hostile', and 'This Love'. Geezer Butler, of the legendary BLACK SABBATH, joined all of the “Metal Masters” on stage for the finale of 'Hole In The Sky'.

“We’re extremely excited to be bringing the Metal Masters series back home to the East Coast with our most diverse and talented lineup to date,” says Mark Menghi, Samson’s Director of Marketing. “I say it every time and this time will be no different, but Metal Masters 4 is going to be the best one yet...”
