"I think the trick with 'Dystopia' was sort of fine-tuning it and bringing all those elements together.
"Because you can't be the band you were on your debut record, and you're not even gonna be the band you were on your last record, because life moves forward and development happen.
"And Chris Adler was a big part of helping 'Dystopia' get focused.
"And Kiko [Loureiro] coming in brought that... Megadeth's always had two - Dave [Mustaine] and then this other juxtaposed guitar player, and I think Kiko really complemented that well. And live, Kiko's an incredible performer as well."
Ellefson also noted about "Dystopia":
"We probably worked on it for almost a year before we recorded it. And it took another six months or so, probably, to cut the record.
"It went through a lot of transitional things to get it to just kind of boil it down to the essence of what it really is. And I think what fans are happy about is they like to hear us being this Megadeth that they grew up with.
"We've done a lot of different things in our career. We're a band that can write really intricate riffs, we're a band who can write great choruses and hooks."
