Megadeth's upcoming record will follow-up the successful "Endgame" and comes after their recent legendary festival shows as part of the "Big Four" alongside Metallica, Slayer and Anthrax. Writing/arranging, drum tracking, guitars and solos commenced this month at Vic's Garage in San Marcos, CA with most of the process expected to be completed before Megadeth tours this summer as part of the Rockstar Energy Drink Mayhem Festival with Disturbed and Godsmack.
