MEGADETH debuted a brand new song, "Public Enemy No. 1", during the band's headlining performance last night (Monday, July 4) at Docks in Hamburg, Germany.
In introducing the track, MEGADETH mainman Dave Mustaine said from the stage, "I wanted to do something for you tonight to show you how much we appreciate you instead of saying you're a great audience. We're gonna play a new song for you. This song is from our new record, [it's] never been played anywhere, never been heard by anybody but us. This song is called "Public Enemy No. 1"."
