Metal Allegiance was formed by bassist/songwriter/producer Mark Menghi in Long Island in July 2014. Mark shortly after recruited, bassist David Ellefson and drummer Mike Portnoy to perform on Motörhead's Motörboat Cruise for their first ever live appearance as Metal Allegiance, which was described as "a celebration of heavy metal, powered by the almost tribal bond shared between the extreme music community's most revered trailblazers, armed with a list of contributors onstage that read like a Wikipedia entry on the genre itself." All of the band members were longtime friends and had jammed together occasionally, including events such as the Shiprocked Cruise and NAMM; this eventually led to recording an album. It was on the Motörboat Cruise where they enlisted guitarist Alex Skolnick as the final piece to the "Core 4." The result, the eponymous Metal Allegiance, was released on September 17, 2015, and included a number of guests, including vocals by Phil Anselmo, Randy Blythe, Troy Sanders, Chuck Billy, Mark Osegueda, Cristina Scabbia, Matt Heafy, Doug Pinnick, Jamey Jasta, Chris Jericho, Tim "Ripper" Owens, Alissa White-Gluz and Steve "Zetro" Souza, guitar by Heafy, Gary Holt, Phil Demmel, Andreas Kisser, Misha "Bulb" Mansoor, Ben Weinman, Charlie Benante and Ron "Bumblefoot" Thal, and bass by Rex Brown. It was between a span of 9 months where Menghi, Ellefson, Skolnick and Portnoy wrote, recorded, mixed and mastered their debut album while having over two dozen special guests appear on it plus signing a global record deal with Nuclear Blast Entertainment under the careful eye of AR legend Monte Conner. Metal Allegiance received positive reviews worldwide, and performed well on the charts, entering number 143 on the Billboard 200, and number 27 on the Top Rock Albums chart. The band promoted the album by touring at various venues within the United States along with performing at many festivals and one-off appearances like Loud Park Festival in Japan and Bloodstock Festival in the United Kingdom amongst others. Metal Allegiance's next release was a digital only covers EP entitled Fallen Heroes, released on August 12, 2016, as a tribute to then-recently deceased singers Lemmy, David Bowie and Glenn Frey. The EP includes covers of Motörhead's "Iron Fist", Bowie's "Suffragette City" and the Eagles' "Life in the Fast Lane", with vocals provided by Troy Sanders, Mark Osegueda and Alissa White-Gluz respectively. In honor of all of music's Fallen Heroes, Metal Allegiance performed a special "Fallen Heroes" tribute concert at The Grove in Anaheim, California on January 20, 2017 where they exclusively covered music from all of their personal musical heroes whom have passed on. Metal Allegiance released their second album, Volume II - Power Drunk Majesty, on September 7, 2018. In addition to Osegueda and Sanders, guest vocals on this album include Trevor Strnad, John Bush, Bobby "Blitz" Ellsworth, Mark Tornillo, Johan Hegg, Max Cavalera and Floor Jansen. Metal Allegiance is currently working on new material for their third album, which will reportedly include guest appearances by Bobby "Blitz" Ellsworth and Phil Demmel.
