Let's make this birthday one to remember.

60 years old (Born on November 12, 1964)

Happy Birthday, David Ellefson! May your day rock harder than the epic basslines you've unleashed for decades. From Megadeth's thunderous classics to shaking walls with Temple of Brutality, F5's melodic mayhem and Killing Machine’s relentless drive—your sonic mastery remains unmatched.

Whether slaying massive crowds worldwide or crafting riffs that melt speakers, you keep proving why you're eternally "mega." Here's hoping this birthday amps up as loud as your legendary performances. Stay heavy and unstoppable! Keep making necks ache from headbanging because face it—we all gladly endure the whiplash when you're at the helm. Cheers to another crushing year ahead!
