Megadeth debuted a brand new song, “Public Enemy No. 1”, during last night’s (Monday, July 4) headline performance at Docks in Hamburg, Germany. Dave Mustaine commented after the show, “Tonight’s audience was crazy! Thanks for helping me sing and I am so glad we got to do something special for the German audience finally, debuting “Public Enemy”. The track will appear on Megadeth’s 13th studio album, tentatively due to be released this fall. Watch fan-filmed footage of “Public Enemy No. 1” below.
