The pair never worked together in Megadeth. Menza joined Dave Mustaine for 1990 album Rust In Peace and rejoined in 2004 before being fired and replaced by Shawn Drover.

LoMenzo joined in 2006 before being replaced with the band's original bassist David Ellefson in 2010. Menza and LoMenzo's first rehearsal took place in June at Menza's Disintegrator Studios in California where they played through some Megadeth, Metallica and Led Zeppelin tracks.
