The Final Chapter or Hidden Studio Treasures? Dave Mustaine Spills the Details on Megadeth’s Last Album and Vault Surprises!

Dave Mustaine says Megadeth’s self-titled 17th studio album will still be their final full-length record, but that may not necessarily mean fans have heard the last unreleased Megadeth music.

Speaking during a Q&A ahead of the band’s September 24 appearance at the Grammy Museum in Los Angeles, Dave Mustaine explained that Megadeth have accumulated a large amount of unfinished material during recording sessions over the years. Some of those ideas are more than simple riffs.

Dave Mustaine described them as “half-songs” that were left at the end of various recording sessions and could eventually be revisited.

He explained that when the band is recording, new ideas often appear while listening back to songs. Rather than abandoning them, those riffs and fragments are saved at the end of the session so they can potentially be developed later.

Once an album is finished, however, many of those pieces remain untouched. Dave Mustaine now wants to go back through the material left over from the sessions for Megadeth and find out whether any of it is worth completing.

«Maybe we’ll end up discovering some new songs that are left over from the sessions», he said.

He also made an important distinction: Megadeth are not planning another studio album. Any future material would instead come from ideas that have already been recorded.

Dave Mustaine joked that if he discovered something equivalent to “half of ‘Holy Wars’ and half of ‘Black Friday’” sitting in the archives, he would absolutely release it.

His decision to end Megadeth’s studio career remains connected to the worsening condition of his hand. Dave Mustaine has previously spoken about dealing with Dupuytren contracture, which can progressively limit movement in the fingers.

He plans to continue with Megadeth’s farewell run before eventually undergoing surgery, knowing there is no guarantee that the procedure will allow him to keep playing at the same level.

So while another full Megadeth album is still off the table, the archives may have one final surprise or two left in them.

Would you want Megadeth to finish and release those leftover songs, or should the final album remain the true ending?
