Megadeth bassist David Ellefson recently gave a track by track breakdown of their new album 'TH1RT3EN', and says that the title track sums up the entire arc of the band.

Megadeth has had a 28-year long career. It would seem nearly impossible to encapsulate that entire experience into one song, but bassist David Ellefson says the album's closing track does just that. The recently returned bassist told Music Radar of the song '13':

"It really epitomizes the story of Megadeth. Before starting the record, Johnny K had read Dave’s autobiography, and I think that helped him understand Dave’s psyche, as well as what Megadeth is all about. As the song was being developed musically, the words started to spill out onto the page, largely from Johnny’s conversations with Dave. If you ever wanted to hear a song that summed up the arc of Megadeth as a band, '13' is it. The song ends on such a high. Megadeth hasn’t had a big, theatrical kind of song since In My Darkest Hour, so now we’ve got another one with '13'. It’s the perfect ending to a great album."

For more Ellefson's track-by-track analysis of the album, head to Megadeth's symbolic 13th album will arrive in stores November 1st, the same day as former nemesis' Metallica's collaboration album with Lou Reed -- coincidence? The band will also be heading 2012's Gigantour with supporting acts Motorhead, Lacuna Coil, and Volbeat.
