Dave Mustaine has confirmed that TESTAMENT bassist Steve DiGiorgio laid down the bass tracks on the new MEGADETH album, “The Sick, The Dying, And The Dead”. Due on July 8, the follow-up to 2016’s “Dystopia” features a cover of DEAD KENNEDYS‘ “Police Truck” and Sammy Hagar‘s “This Planet’s On Fire”, the latter of which includes vocals from Hagar himself.

The MEGADETH leader shared the news of DiGiorgio‘s involvement in the LP in an interview with Jose Mangin of SiriusXM Liquid Metal. He said: “We obviously had that weird little…well, it wasn’t little, but we had something happen that we needed to make a decision on, and it set us back a little bit timing-wise, because we needed to recalibrate and find someone to perform the bass parts, and we found who I thought was the perfect fit for us while I decided what to do… Do you know who it was? …It was Steve DiGiorgio. You’re the first person I told.”

He continued: “It was a good choice. I didn’t think about anybody else at the time. I was thinking about ‘who’s the hottest guy out there that can play these new songs?’ [Mustaine‘s son] Justis told me one of the fastest songs we’ve ever written is on this record. I don’t care what anybody says — bass may be less strings than guitar, but it’s difficult to play, if you’re like me. I have a real hard time playing the bass. I wrote the riff for ‘Peace Sells… But Who’s Buying?’ for Pete‘s sake, but you know… having to jam some of those parts that fast, it just kills your fingers.”

There has been speculation about DiGiorgio‘s involvement in the new MEGADETH LP since last July, based on a Cameo video Mustaine recorded in which he offered the first glimpse of the bassist that re-recorded David Ellefson‘s bass tracks on the much-anticipated MEGADETH effort. In the clip, the MEGADETH guitarist/vocalist could be seen walking around a studio where he showed engineer Chris Rakestraw sitting behind the studio console as well as the mystery bassist “hiding behind the chair on the floor.” Although it was impossible to tell who the bassist was based on the video, the musician appeared to be using the same brand of Ibanez bass played by DiGiorgio.

DiGiorgio is widely renowned as a pioneer on the fretless bass in heavy metal music, having played with TESTAMENT, DEATH and SADUS, among others. Within his genre, Steve is respected for his playing skills, versatility and incredible technique. He has more than 40 studio album recordings and over 20 years of touring the world.

Two months ago, Mustaine confirmed that James LoMenzo will play bass for MEGADETH when the band returns to the road in April for the second U.S. leg of “The Metal Tour Of The Year”. Joining them will be co-headliners LAMB OF GOD along with special guests TRIVIUM and IN FLAMES.

LoMenzo joined MEGADETH in 2006 and appeared on two of the group’s studio albums, 2007’s “United Abominations” and 2009’s “Endgame”. He was fired from the band in 2010 and replaced with returning original MEGADETH bassist David Ellefson.

In addition to MEGADETH, LoMenzo has played with Ozzy Osbourne, Zakk Wylde and WHITE LION. For the past nine years, LoMenzo has been performing with iconic rocker John Fogerty.

LoMenzo played his first show with MEGADETH in nearly 12 years last August in Austin, Texas. The concert took place three months following Ellefson‘s dismissal from MEGADETH after sexually tinged messages and explicit video footage involving him were posted on Twitter.

Ellefson laid down his bass tracks on MEGADETH‘s sixteenth LP in May 2020 at a studio in Nashville, Tennessee. A short time later, he raved about his performance on the record, telling the 96.7 KCAL-FM radio program “Wired In The Empire” that his musical chemistry with MEGADETH drummer Dirk Verbeuren was comparable to the interplay between Geddy Lee and Neil Peart on classic RUSH albums. “I feel like on the new MEGADETH record, me and Dirk have those same moments,” he said. “It’s MEGADETH — it’s not RUSH, obviously — but in the field of what we do, there were these moments that I was just going, ‘Oh, my God.’ This is me as a kid going, ‘This is my Geddy/Neil moment right here.'”

In June 2021, Mustaine announced during an episode of his Gimme Radio program “The Dave Mustaine Show” that Ellefson‘s bass tracks would not be used on the new MEGADETH LP.

Ellefson was in MEGADETH from the band’s inception in 1983 to 2002, and again from 2010 until his latest departure.
