According to Dave Mustaine,the new batch of songs includes a ballad about his past beef with bassist David Ellefson… which Ellefson will sing.
The two used to have a pretty rocky relationship, which they’ve worked out in recent years. Mustaine says he suggested the idea to Ellefson, figuring he should go ahead and write a song about it directly instead of secretly writing lyrics about it.
“If it doesn’t get on this record, I’m going to try to work on it on the next record,” adds Mustaine. “Because it was actually really cool to see Ellefson writing something and hear him sing.”
