This is a project aimed at making it easy to see who inspired the bands you love or even hate. For this I try not to use any influences that the band don’t claim themselves. There will be a focus on predecessors but successors will be added as they site the band. These trees become more and more interactive as new bands are added, allowing you to click any band that has a tree and jump to it.

We want our lists to be better. If you know something that belongs on this list, let us know. When in doubt we will leave it out, so we need reliable sources.

Megadeth are the thrash metal band formed by guitarist / singer / primary song writer, Dave Mustaine after being booted from Metallica shortly before recording their first album. This was not before Dave made his mark on the early years of that band. Along side the earlier members of Metallica, Dave Mustaine should be considered with equal respect in regards to the innovation of thrash metal. Following his firing, Dave went on to form one of the biggest most influential thrash bands.
Perhaps more than most bands, Megadeth has had a rotating door of members with Mustaine being the only consistent member. The first few years of Megadeth was a process of finding the right members for the band to kick off with the first notable line up being Dave, David Ellefson on bass, Chris Poland on guitar, and Gar Samuelson on drums. The first two albums were done with this line up with all song writing credits belonging to Dave.
The Third album would see replacements for Chris and Gar with Jeff Young on guitar, and Chuck Behler on drums. This album would be the first to feature a few co-writing credits from Ellefson, but otherwise songs are credited again to Dave.
The fourth album Rust in Peace would see the beginning of the only steady line up of Megadeth and would produce four albums in total. Marty Friedman would fill the guitar role with Nick Menza on drums. Rust in Peace was mostly written, again, by Mustaine with a co-writing credit and one full credit for a short song by Ellefson. For the next three albums though this line up would all have writing credit to some degree.

Greg Howe

Dave Mustaine said growing up he was around British Invasion stuff and Motown which he say he thinks influenced some of the rhythm of Megadeth. Dave said that the jazzy swing of Megadeth comes from his Motown influences he had as a kid. After Malcom Young has Dave’s biggest rhythm guitar influence he said any of the new wave of British heavy metal guys would have been second such as players form Diamond Head, Judas Priest, or Iron Maiden.

Dave Ellefson played in jazz band as a kid.

Before joining Megadeth, Gar and Chris played together for years and had most recently played together in a jazz fusion band called the New Yorkers. Dave said in an interview that Gar’s jazz style had a big impact on the dynamics of their songs at the time. Chris said him and Gar went from playing Deep Purple to the fusion stuff and wanted to be like John Mclaughlin and Brand X. Chris named Gar’s influences as Billy Cobham and Tony Williams, and Lenny White. Chris said they were both rock guys first who were later influenced by fusion guys. Although Chris and Gar were not part of the song writing in Megadeth, their jazz style had an influence on the sound during their period. (their influences are not listed in the main list because their influence on the Megadeth sound was temporary and don’t reflect the core sound of Megadeth which is carried forward without them.)

Chris Poland said as a kid he learned a little blues and folk guitar from his mom before learning to play piano from his aunt. He then was influenced to play guitar again by his older cousin who was playing guitar who played blues and rock stuff. He said he first took a real interest in guitar after hearing the first Led Zeppelin and Cream albums. He also was a fan of Jethro Tull, Hendrix, and Mountain. He was then influenced by Jeff Beck with his albums Truth and Jeff Beck Group. He also named Mahavishnu Orchestra, Weather Report, and anything Jeff Beck and Stanley Clarke, Robin Trower, and Jaco Pastorius.

Jeff Young appearing for lead guitar on So Far, So Good.. So What!, named influences as Montrose, Judas Priest, Black Sabbath, Iron Maiden, Allan Holdsworth, Shawn Lane, Eric Johnson, Steve Morse, and Paco de Lucía.

I’m unsure who influenced Chuck Behler.

Marty past his time in Megadeth was later influenced by Aya Matsuura. He also said he has been influenced by non guitar music such as “Indian ragas, Chinese Erhu music, Japanese flute and koto music, Okinawan music, Turkish and Iranian violin music”

Besides the influences listed above, Nick’s Wikipedia lists several other jazz drummer besides Buddy Rich. However, at the time of writing this web archive is down which has the original source. For now I will leave those drummer of the list until can verify them to be correct.

Al named influences as: The Allman brothers (Duane Allman, Dickie Betts), Jeff Beck, Jimmy Page, Gary Moore, and The Beatles. He’s also a fan of Paul Rodgers/Bad Company, Elton John, Emerson, Lake, and Palmer, Tower of Power, AC/DC, Van Halen, Disney’s Fantasia

He in particular named being a fan of Supertramp and Kansas. Shawn also plays guitar and named early influences as Pat Travers, Eddie Van Halen, and Ritchie Blackmore.

Chris Broderick named influences ranging from Dokken, Van Halen, Metallica, King Diamond, Pantera, Meshuggah, and Revocation. He named guitarists Eddie Van Halen, Yngwie Malmsteen, Paul Gilbert, Jason Becker, Marty Friedman, Greg Howe, Scott Mishoe, Andres Segovia, Pepe Romero, Al Di Meola, and flamenco guys like Paco De Lucia, Paco Peña and guys like that. He also named Chet Atkins and Danny Gatton, and more recenlty Johnny Hiland. He also named Bach’s counter point as an influence on approaching Megadeth harmonies. His Jackson profile also lists John Petrucci, Richardo Iznaola, Djanjo Reinhardt and Wes Montgomery.

Kiko said the same year he got is first electric guitar Queen, Iron Maiden, Ozzy, Scorpions, AC/DC, and Whitesnake all played Rock in Rio which got him much more seriously into guitar. He also names being a fan of jazz guys like Wayne Shorter, Coltrane, Miles Davis, and Charlie Parker. In a 2009 interview when asked what he was listening to he named a veriety of stuff ranging from “Paco de Lucia, Yamandu Costa, Marco Pereira, Marco Tardelli and also some jazz like John Coltrane or Wayne Shorter. Jeff Beck – always.
Some bands like Mesugahh, Tool, King Crimson.” His website bio also names Herbie Hancock and Brazilian musician Hermeto Pascoal

Dirk only shared credit on a single song. He lists influences as Dave Lombardo, Mick Harris, Sean Reinert, Steve Flynn, Mike Smith, Chad Smith, Pete Sandoval, Napalm Death, Godflesh, Beastie Boys, Björk. He also names albums which he listened to a lot as “Consuming Impulse (Pestilence), Speak English Or Die (S.O.D.), early Nuclear Assault and Metallica, Symphonies Of Sickness (Carcass), World Downfall (Terrorizer), Darkness Descends (Dark Angel) and pretty much everything Earache released in the late 80s/early 90s.”
